security/vboot: Allow files to go into only RW-A or RW-B region
The AMD firmware package created by amdfwtool contains pointers to the
various binaries and settings. This means that we need different copies
of the package in each region.
This change allows for the different files in each of the 3 vboot
regions.
BUG=b:158124527
TEST=Build trembyle; see the correct versions of the files getting
built into the RW-A & RW-B regions.
