Hello build bot (Jenkins), Marc Jones, Patrick Rudolph, Jonathan Zhang, Rocky Phagura, Jingle Hsu, Angel Pons, Arthur Heymans, Morgan Jang,

I'd like you to reexamine a change. Please visit

cpu/x86/smm: Add smm_board_info for SMM that can be set from mainboard

This u32 smm_board_info is an optional per mainboard defined data that
mainboard can set the value and pass to SMM. The reason is that getting
certain data that requires searching from flash VPD or CMOS is not very
ideal to be done in SMM.

One use case is that mainboard can pass SMM console log level via this
variable and in SMM it can be referenced in get_console_loglevel()
override function directly.

Tested=On OCP Delta Lake, verified SMM log level can be overridden.
