2021-03-26soc/intel/alderlake: Add provision to override Rcomp settingsSubrata Banik
Add function to allow overriding the RcompResistor and RcompTarget UPDs from mainboard if required. Mainboard users can pass required rcomp from memory.c file. Refactor ddr_config structure to take out rcomp related variable outside for all memory type to override if required. BUG=b:182772421 TEST=Able to override the default RcompResistor and RcompTarget values.

2021-03-26soc/intel/alderlake: Align RcompResistor definition as per MRCSubrata Banik
List of changes: 1. Alder Lake MRC is expecting a RcompResistor value of word width. Reference RCOMP resistors on motherboard are ~ 100 Ohms but coreboot is passing an array of RcompResistor which is not completely in use. Note: Rcomp resistor value represents rcomp resistor attached to the DDR_COMP pins on the SoC. 2. Also, remove usage of '&' with memcpy the required value into RcompTarget array. 3. Also, update RcompResistor value for ADLRVP. BUG=b:183341229 TEST=Enable FSP debug log to verify the override value for RcompResistor is reflecting correctly.
