[Jamie Chen (Code Review)]

Hello Patrick Rudolph, Kane Chen, build bot (Jenkins), Patrick Georgi, Martin Roth,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/35040

to look at the new patch set (#2).

Change subject: intel/common/mmc: Provide mmc.c for setting dll registers.
......................................................................

intel/common/mmc: Provide mmc.c for setting dll registers.

Currently, we don't have UPDs to set emmc settings per mainboard on CML.

This code change is to create mmc.c to provide interface to override dll
settings per mainboard.
Notice: mainboard_get_mmc_dll function will override the dll values in FSP.

BUG=b:131401116
BRANCH=none
TEST=Boot to OS and confirm the dll values have been overrided.
