make firmware/dsp56k/bootstrap.asm buildable on a56
Make firmware/dsp56k/bootstrap.asm buildable on a56, the free Motorola
DSP56001 assembler (http://www.zdomain.com/a56.html).
Summary of changes:
- Remove '<' and '>' candy (they specify explicit addressing modes,
which a56 don't grok, but uses implicitly anyway).
- Replace 'move' with 'movem' when accessing program memory.
- Rename a few labels to avoid duplicates (which a56 can't handle).
