dm: pass vrpmb key via cmos interface

Browse Source 
CMOS offset from 0x20 to 0x9F is used to store rpmb key information.
vsbl loader will init vrpmb key in CMOS when boot/reboot.
vsbl loader will not init vrpmb key during S3 resume.
vsbl will read vrpmb key via CMOS interface.
After reading, the key value is cleared in CMOS. So the key can only be
read once until next boot.
