soc/mediatek/mt8196: Add SD card configurations

Rauru reference design has SD card interfaces, so we have to configure
it in ramstage.

Implement msdc.c (memory and SD Card controller) to place the SD card
drivers.

This implementation is based on chapter 10.3 in MT8196 Functional
Specification.

TEST=Build pass
BUG=b:317009620
