Hello build bot (Jenkins), Furquan Shaikh, Tim Wawrzynczak, Angel Pons, Patrick Rudolph, EricR Lai,

to look at the new patch set (#7).

soc/intel/alderlake: Add provision to override Rcomp settings

Add function to allow overriding the RcompResistor and
RcompTarget UPDs from mainboard if required.

Mainboard users can pass required ddr_config from memory.c file.

Note: LPDDR5 is intentionally left as-is in this change because
`ddr_config` and `lp5x_config` are members of the same union, and
their storage space overlaps. Thus, it is not possible to use
both of them at the same time to store settings.

BUG=b:182772421
TEST=Able to override the default RcompResistor and RcompTarget
values.
