mb/ocp/deltalake: Add EWL Hob processing for MRC error

Override the weak function mainboard_ewl_check() and
select OCP_EWL. The Intel FSP needs to disable promote
MRC Warnings otherwise FSP won't return after MRC error.
The official public CedarIsland FSP doesn't provide this
via UPD.

Tested=On OCP Deltalake, with a customized FSP that disabled
promote MRC Warnings, connected with a faulty DIMM can see
EWL type 3 error being generated.
