vc/amd/pi/0067F00: add option to add AGESA binary PI as stage
Stage addition to CBFS allows relocation to happen on the fly. Take
advantage of that by adding AGESA binary PI as a stage file so that
each instance will be relocated properly within CBFS. Without this
patch Chrome OS having multiple CBFS instances just redirects the
AGESA calls back into RO which is inappropriate.
BUG=b:65442265,b:68141063
TEST=Enabled AGESA_BINARY_PI_AS_STAGE and used ELF file. Booted and
noted each instance in Chrome OS build was relocated.
