mb/intel/archercity_crb: Add EWL Hob processing for MRC error 

Override the weak function mainboard_ewl_check() and select OCP_EWL.

Select IPMI_KCS_ROMSTAGE and IPMI_OCP for OCP IPMI commands which are
needed for OCP EWL driver, but they are Meta-specific BMC commands
and don't really work for AC, this change is just for a demonstration
with AC.

Note that FSP UPD promoteWarnings needs to be disabled so that
FSP won't block and can return to coreboot for EWL processing
when memory EWL type 3 error occurs.

Tested=On Intel AC, connected with a faulty DIMM can see
EWL type 3 error being generated and halted with coreboot log:
