Hello Ravi kumar, build bot (Jenkins), mturney mturney, Julius Werner,

I'd like you to reexamine a change. Please visit

to look at the new patch set (#6).

Change subject: selfboot: Add support for selfload in romstage
......................................................................

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.
