util/amdfwtool: Write EFS and AMDFW body in separate files
Add support to write EFS and AMDFW body to separate files. This is done
through passing an optional --body-location parameter to the amdfwtool.
If that option is not passed, then EFS will be written in the same file
as the AMDFW body. This will help to keep the minimum data to be
loaded/mapped from CBFS in PSP verstage.
BUG=None
TEST=Build and boot to OS in Skyrim.
