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.
