Commit 5b4258f672 ("misc: rtsx: rts5249 support runtime PM")
uses "rtd3_work" and "idle_work" to manage it's own runtime PM state
machine.
When its child device, rtsx_pci_sdmmc, uses runtime PM refcount
correctly, all the additional works can be managed by generic runtime PM
helpers.
So consolidate "idle_work" and "rtd3_work" into generic runtime idle
callback and runtime suspend callback, respectively.

There's interrupt immediately raised on rtsx_pci_write_register() in
runtime resume routine, but the IRQ handler hasn't registered yet.
So we can either move rtsx_pci_write_register() after rtsx_pci_acquire_irq(),
or just stop mangling IRQ on runtime PM. Choose the latter to save some
CPU cycles.

1.RTS5261 work in SD mode and set MMC_CAPS2_SD_EXP flag.
2.If card is plugged in, Host send CMD8 to ask card's PCIe availability.
3.If the card has PCIe availability and WP is not set, init_sd_express() will be invoked,
RTS5261 switch to PCIe/NVMe mode.
4.Mmc driver handover it to NVMe driver.
5.If card is unplugged, RTS5261 will switch to SD mode.

Drivers should not use legacy power management as they have to manage power
states and related operations, for the device, themselves. This driver was
handling them with the help of PCI helper functions like
pci_save/restore_state(), pci_enable/disable_device(), etc.
With generic PM, all essentials will be handled by the PCI core. Driver
needs to do only device-specific operations.
The driver was also using pci_enable_wake(...,..., 0) to disable wake. Use
device_wakeup_disable() instead.
Compile-tested only.

DMA transfers to and from the SD card stall for 10 seconds and run into
timeout on RTS5260 card readers after ASPM was enabled.
Adding a short msleep after disabling ASPM fixes the issue on several
Dell Precision 7530/7540 systems I tested.
This function is only called when waking up after the chip went into
power-save after not transferring data for a few seconds. The added
msleep does therefore not change anything in data transfer speed or
induce any excessive waiting while data transfers are running, or the
chip is sleeping. Only the transition from sleep to active is affected.

Several helper functions are local to the source and do not
need to be in global scope, so make them static.
Cleans up sparse warnings:
symbol 'rtsx_pm_power_saving' was not declared. Should it be static?
symbol 'rtsx_set_l1off_sub_cfg_d0' was not declared. Should it be static?
symbol 'rtsx_pm_full_on' was not declared. Should it be static?
symbol 'rtsx_comm_set_ltr_latency' was not declared. Should it be static?
symbol 'rtsx_pci_process_ocp' was not declared. Should it be static?
symbol 'rtsx_pci_process_ocp_interrupt' was not declared. Should it be
static?

A change to the generic scatterlist code caused a conflict with
the rtsx card reader driver:
In file included from drivers/misc/cardreader/rtsx_pcr.c:32:
include/linux/rtsx_pci.h:40: error: "SG_END" redefined [-Werror]
This changes one instance of the driver to prefix SG_END and
related constants.
Fixes: 723fbf563a ("lib/scatterlist: Add SG_CHAIN and SG_END macros for LSB encodings")

Add support for new chip rts5260.
In order to support rts5260, the definitions of
some internal registers and workflow have to be
modified and are different from its predecessors
and OCP function is added for RTS5260. So we need
this patch to ensure RTS5260 can work.

Because Realtek card reader drivers are pcie and usb drivers,
and they bridge mmc subsystem and memstick subsystem, they are
not mfd drivers. Greg and Lee Jones had a discussion about
where to put the drivers, the result is that misc is a good
place for them, so I move all files to misc. If I don't move
them to a right place, I can't add any patch for this driver.
