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).
