intel/skylake: Create "RtcLock" Silicon UPD from coreboot
FSP should not lock CMOS unconditionally. coreboot sends Silicon
UPD parameter "RtcLock" to FSP to take action on CMOS
region locking/un-locking. This patch has CB generic code for
creating the Silicon UPD paramater.
BUG=chrome-os-partner:44484
BRANCH=none
TEST=Build and booted in kunimitsu, tested using below command-
When DIsabled RtcLock from devicetree in coreboot, booted to kernel
and run following commands -
>> crossystem fw_result=success
>> crossystem | grep fw_result
It should reflect the value that is set. Here, success.
If ENabled RtcLock from Coreboot devicetree, The same commands will
fail to update the fw_result status from crossystem utility.
