broadwell: Preparations for building

Updated Intel Broadwell for differences in the source based on
the chromium tree. It is missing most of the recent updates
on coreboot.org.

- makefile changes for Elog and IDF tool
- kconfig changes for ME, ucode, and other updates
- update oprom flag
- update timestamp mechanism
- cbfs payload function is now generic
