Wei WANG 773ccdfd9c mfd: rtsx: Read vendor setting from config space
Normally OEMs will set vendor setting to the config space of Realtek
card reader in BIOS stage. This patch reads the setting at the first,
and configure the internal registers according to it, to improve card
reader's compatibility condition.

Wei WANG 4c4b8c105a mfd: rtsx: Support RTS5249
RTS5249 supports SD UHS-II interface.

In order to support SD UHS-II,the definitions of some internal
registers of RTS5249 have to be modified and are different from its
predecessors. So we need this patch to ensure RTS5249 can work, even
SD/MMC stack doesn't support UHS-II interface.

Wei WANG eebbe25416 mfd: rtsx: Use macros to replace some variables
In function rtsx_pci_switch_clock, some variables, such as min_n, max_n,
and max_div, are not necessary. And those assigned values look very
obscure for others. It's more proper to use macro definitions here to
replace these variables.
