mmc: rtsx: Let MMC core handle runtime PM
commit
7570fb41e450ba37bf9335fe3751fa9f502c30fa upstream.
Since MMC core handles runtime PM reference counting, we can avoid doing
redundant runtime PM work in the driver. That means the only thing
commit
5b4258f6721f ("misc: rtsx: rts5249 support runtime PM") misses is
to always enable runtime PM, to let its parent driver enable ASPM in the
runtime idle routine.
