Revert "soc/intel/broadwell: Drop vboot support"
This reverts commit f87489bbae5bb1ae3b17b6a03af9e309769b1f72. Reason for revert: Broadwell actually supports early flash writes.

+ Broadwell can either start verstage in a separate stage
+ right after the bootblock has run or it can start it
+ after romstage for compatibility reasons.
+ Broadwell however uses a mrc.bin to initialize memory which
+ needs to be located at a fixed offset. Therefore even with
+ a separate verstage starting after the bootblock that same
+ binary is used meaning a jump is made from RW to the RO region
+ and back to the RW region after the binary is done.
