Revert "soc/intel/adl: Skip sending MBP HOB to save boot time"
This reverts commit 9a7fbbc98e8610a0a5314470edd8d5dafe676a06.
SkipMbpHob UPD skips generation of MBP Hob within FSP. Skipping MBP
Hob generation also skips syncing correct version of chipset
data with CSE since FSP uses version information from MBP HOB.
In absence of MBP Hob, FSP is unable to get version information and
hence chipset data sync is skipped.
This creates an issue while platform tries to enter deeper sleep
states.
BUG=b:215448362
BRANCH=None
TEST= FSP can get version information from MBP HOB and chipset sync
is performed. It has been Verified using FSP debug logs on Brya
board.
