intel/common/block/scs: Add ability to send early CMD0, CMD1

Browse Source 
In order to improve boot time with emmc, add ability to send CMD0
and CMD1 early in romstage. This way, by the time system boots to
payload, we are ready to continue with emmc setup and we don't need
to send CMD0 in payload again, and wait for card to reset and be ready.

BUG=b:78106689
TESTS = Boot to OS
	Force early_mmc_wake_hw() to return error, recover in payload
	Force an error in payload, make sure system can recover/boot
