mb/google/brya/var/nereid: Enable OZ711LV2LN SD card controller
Select the Bayhub LV2 driver, and implement power sequencing as per the
datasheet.
BUG=b:223304542
TEST=Check that connecting an SD card works as expected in the OS. Probe
the EN and RST signals and check the timing requirements are met.
