Now that there is only 1 c-file left of the intel_cht_int33fe code,
move it to the intel directory instead of it having its own int33fe
sub-directory.
Note this also renames the module from intel_cht_int33fe_typec to
intel_chtwc_int33fe, to better match the names of other PMIC related
modules like the intel_chtdc_ti_pwrbtn module.

The intel_cht_int33fe driver is intended to deal with ACPI INT33FE
firmware-nodes on Cherry Trail devices with a Whiskey Cove PMIC.
The original version of the driver only dealt with the GPD win and
GPD pocket boards where the WC PMIC is connected to a TI BQ24292i charger,
paired with a Maxim MAX17047 fuelgauge + a FUSB302 USB Type-C Controller +
a PI3USB30532 USB switch, for a fully functional Type-C port.
Later it was split into a Type-C and a Micro-B variant to deal with
the Lenovo Yoga Book YB1-X90 / Lenovo Yoga Book YB1-X91 boards where
the ACPI INT33FE firmware-node only describes the TI BQ27542 fuelgauge.
Currently the driver differentiates between these 2 models by counting
the number of I2cSerialBus resources in the firmware-node.
There are a number of problems with this approach:
1. The driver autoloads based on the acpi:INT33FE modalias causing it
to get loaded on almost all Bay Trail and Cherry Trail devices. It
checks for the presence of a WC PMIC, so it won't bind but the loading
still wastes time and memory.
2. Both code paths in the driver are really only designed for a single
board and have harcoded various assumptions about these boards, if
another design matching the current checks ever shows up the driver
may end up doing something completely wrong.
Avoid both issues by switching to using DMI based autoloading of
the module, which has neither of these problems.
Note this splits the previous intel_cht_int33fe kernel module into two
modules: intel_cht_int33fe_typec and intel_cht_int33fe_microb, one for
each model.

2. Update the dev_name on the Asus ME176C and TF103C to reflect that these

As part of the probing process, asus_wmi_evaluate_method_buf is called

instead of ASUS_WMI_UNSUPPORTED_METHOD. This 0 is transformed to

Add support for spi bus in serial-multi-instantiate driver
Some peripherals can have either a I2C or a SPI connection
to the host (but not both) but use the same HID for both
types. So it is not possible to use the HID to determine
whether it is I2C or SPI. The driver must check the node
to see if it contains I2cSerialBus or SpiSerialBus entries.
For backwards-compatibility with the existing nodes I2C is
checked first and if such entries are found ONLY I2C devices
are created. Since some existing nodes that were already
handled by this driver could also contain unrelated
SpiSerialBus nodes that were previously ignored, and this
preserves that behavior. If there is ever a need to handle
a node where both I2C and SPI devices must be instantiated
this can be added in future.

The call sequence suggested that misc_device /dev file can be opened
before misc device is yet to be registered, which is done only once.
Here punit_misc_dev_lock was used as common lock, to protect the
registration by multiple ISST HW drivers, one time setup, prevent
duplicate registry of misc device and prevent load/unload when device
is open.
We can split into locks:
- One which just prevent duplicate call to misc_register() and one
time setup. Also never call again if the misc_register() failed or
required one time setup is failed. This lock is not shared with
any misc device callbacks.
- The other lock protects registry, load and unload of HW drivers.
Sequence in isst_if_cdev_register()
- Register callbacks under punit_misc_dev_open_lock
- Call isst_misc_reg() which registers misc_device on the first
registry which is under punit_misc_dev_reg_lock, which is not
shared with callbacks.

The driver as originally submitted accidentally relied on Android having
run before and Android having unmasked the 2nd level IRQ-mask for the
charger IRQ. This worked since these are PMIC registers which are only
reset when the battery is fully drained or disconnected.
Fix the charger IRQ no longer working after loss of battery power by
properly setting the 2nd level IRQ-mask for the charger IRQ.
Note this removes the need to enable/disable our parent IRQ which just
sets the mask bit in the 1st level IRQ-mask register, setting one of
the 2 level masks is enough to stop the IRQ from getting reported.

The Surface Go 3 needs some board data in order to configure the
TPS68470 PMIC - add entries to the tables in tps68470_board_data.c
that define the configuration that's needed.

Add a driver for the keyboard, touchpad and USB port of
the keyboard dock for the Asus TF103C 2-in-1 tablet.
This keyboard dock has its own I2C attached embedded controller
and the keyboard and touchpad are also connected over I2C,
instead of using the usual USB connection. This means that the
keyboard dock requires this special driver to function.

The whitelabel (sold as various brands) TM800A550L tablets's DSDT contains
a whole bunch of bogus ACPI I2C devices and the ACPI node describing
the touchscreen is bad (the IRQ is missing). Enumeration of these is
skipped through the acpi_quirk_skip_i2c_client_enumeration().
Add support for manually instantiating the (now) missing I2C devices by
adding the necessary device info to the x86-android-tablets module,
including instantiating an actually working i2c-client for
the touchscreen.

Since the x86-android-tablets code does all it work from module_init() it
cannot use -EPROBE_DEFER to wait for e.g. interrupt providing GPIO-chips
or PMIC-cells to show up.
To make sure things will still work when some necessary resource providers
are build as module allow the per board info to specify a list of modules
to pre-load before instantiating the I2C clients.
