[Arthur Heymans (Code Review)]

Hello build bot (Jenkins),

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

to look at the new patch set (#4).

Change subject: nb/intel/*: Account for cbmem_top alignment

nb/intel/*: Account for cbmem_top alignment

Having cbmem floating between two ram regions is a bad idea and some
payloads (e.g. tianocore) even bail out on this. To overcome this issue mark the
region between tom and cbmem as uma.
