- renamed files where sparc64 used identical names to *_32.c/S
- added a few new Kconfig symbols to simplify logic in Makefile
- refactored Makefile
- Use _$(BITS) for renamed files
- Use CONFIG_SPARC32 for sparc32 specific files
- Use new helpers for SMP and PCI files - to prepare for sparc64 merge
