The equivalent of both of these are now done via macro magic when
the relevant register calls are made. The actual structure
elements will shortly go away.

GPIO handling code has been removed from the drivers (since
this is now handled by the ACPI core) in commit 0f0796509c ("iio:
remove gpio interrupt probing from drivers that use a single interrupt").
Remove the include for linux/gpio/consumer.h since it is no longer
used.

Commit 845c877009 ("i2c / ACPI: Assign IRQ for devices that have
GpioInt automatically") automatically assigns the first ACPI GPIO
interrupt in client->irq, so we can remove the probing code from
drivers that use only one interrupt.

Since commit dab472eb93 ("i2c / ACPI: Use 0 to indicate that
device does not have interrupt assigned") 0 is not a valid i2c
client irq anymore, so change all driver's checks accordingly.
The same issue occurs when the device is instantiated via device tree
with no IRQ, or from the i2c sysfs interface, even before the patch
above.

The I2C core always reports the MODALIAS uevent as "i2c:<client name"
regardless if the driver was matched using the I2C id_table or the
of_match_table. So the driver needs to export the I2C table and this
be built into the module or udev won't have the necessary information
to auto load the correct module when the device is added.

Add data-ready interrupts and trigger support for STK8BA50.
Additional changes:
- read_accel now returns raw acceleration data instead of the
sign_extend32 value
- read_raw will now enable/disable the sensor with each reading
