armv7: add a wrapper for romstage's main() for ARM ISA

This adds a wrapper around main() in romstage which is compiled using
    -marm. This assumes that the bootblock branches to romstage in ARM
    mode.

The long-term idea is to enforce ABI compatibility when handing off to
    the next stage by using shims which are which are compiled in a pre-
    determiend manner and leave the main portions of each stage up to
    whatever the compiler wants. So it will eventually look like this:
    1. bootblock_main (ARM/Thumb)
    2. bootblock_exit (ARM)
    3. romstage_entry (ARM)
    4. romstage_main (ARM/Thumb)
