soc/intel/alderlake: Align RcompResistor definition as per MRC
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.
