Change in coreboot[master]: boardid: Minor clean up and standardization

[Julius Werner (Code Review)]

Change subject: boardid: Minor clean up and standardization
......................................................................

boardid: Minor clean up and standardization

Merge the different coreboot table strapping ID structures into one
because they're really just all the same, and I want to add more. Make
the signature of the board_id() function return a uint32_t because
that's also what goes in the coreboot table. Add a printk to the generic
code handling strapping IDs in ramstage so that not every individual
mainboard implementation needs its own print. (In turn, remove one such
print from fsp1_1 code because it's in the way of my next patch.)
