Add allocation of a buffer for pvmfw within cbmem

Browse source 
Add an allocation of an empty buffer for the Android protected virtual
machine firmware within cbmem. The buffer will be filled by the payload
and the purpose is to just reserve the memory. cbmem is used to make
sure that the region won't overlap with other reserved regions
or device regions.

TEST=depthcharge receives the buffer through lib_sysinfo
BRANCH=main
