soc/intel/mtl: Call cse_fill_bp_info early in romstage
Intel Platform Service Record(PSR) will be enabled on Meteor Lake
platforms. cse_fw_sync actions happen in ramstage when PSR is enabled.
To avoid the boot time penalty of sending the cse_get_bp_info in
ramstage, call cse_fill_bp_info to get cse_bp_info response early in
romstage and store in cbmem. This data can be later used in ramstage.
BUG=b:273207144
TEST=Verify cse_bp_info is filled in romstage in rex.
