[SRU][PATCH 0/5][OEM-5.17][RESEND] Add proper runtime PM support to Realtek PCIe cardreader

[Aaron Ma]

BugLink: https://bugs.launchpad.net/bugs/1963615

[Impact]
New generations of Realtek PCIe card reader cannot detect card insertion
when the device is in PCI D3.

[Fix]
Rework the runtime PM flow and add chip specific support.

[Test]
With the series applied, the device can detect card insertion when it's
in PCI D3.

[Where problems could occur]
System wide power management with less usage like hibernation, kexec
reboot, etc. are not tested extensively. So these cases may be affected.

Resend for OEM-5.17.
MMC patches were already merged by stable update.
