selfboot: Add support for selfload in romstage
Since bootmem is not available in romstage, calls to bootmem APIs need
to be compile-time eliminated in order to avoid linker error:
undefined reference to `bootmem_region_targets_type
BUG=None
BRANCH=None
TEST=./util/abuild/abuild -p none -t GOOGLE_HEROBRINE -x -a -B
cherry-picked on top of CB:49392 and verified successful
compilation.
