The Sideband Acces locking code is skipped from FSP by setting an FSP-S UPD called PchSbAccessUnlock. This locking is being done in coreboot during finalize.c. This is done because coreboot was failing to disable HECI1 device using Sideband interface during finalize.c if FSP already locks the Sideband access mechanism before that. So, as a solution, coreboot passes an UPD to skip the locking in FSP, and in finalize.c, after disabling HECI, it removes the Sideband access.

And split the above programming into into smaller functions. Also, as part of bootblock_pch_early_init we enable decoding for HPET range. This is needed for FspMemoryInit to store and retrieve a global data pointer. And also move P2SB related definitions to a new header file.
