This patch adds a optional reset management for msdc. Sometimes the bootloader does not bring msdc register to default state, so need reset the msdc controller.

Thanks for posting the fix to Mainline
imho this should contain a fixes-Tag as it fixes eMMC-Access on mt7622/Bpi-R64
before we got these Errors on mounting eMMC ion R64:
[ 48.664925] blk_update_request: I/O error, dev mmcblk0, sector 204800 op 0x1:(WRITE) flags 0x800 phys_seg 1 prio class 0 [ 48.676019] Buffer I/O error on dev mmcblk0p1, logical block 0, lost sync page write
Fixes: 966580ad236e ("mmc: mediatek: add support for MT7622 SoC") Tested-By: Frank Wunderlich frank-w@public-files.de
and it needs to be fixed at least for 5.4+, so adding stable-CC
