Subject: ARMv7: Drop XIP relocation code for romstage

It was never used, because we pushed romstage_null into the CBFS
instead of romstage_xip. It's not surprising this worked, but it
was a crude hack. Get rid of all the intermediate objects that are
not needed.

This could probably be further simplified to use the default cbfs
mechanism in our build system instead of having a specific rule for
romstage, but that's for another day.
