Log Message:
Streamline pre-main() prologue just a bit:
- Enable the on-chip caches for 68020 and 68030 in the MMU-enablement
  code fragment, as is already done for 68040 and 68060.  Eliminates
  a bunch of duplicated code in each locore.s.
- The ATC (and the HP MMU TLB, if applicable) has already been flushed /
  invalidated as part of enabling the MMU, so there's no need to either
  call _TIBA() or perform an inline pflusha again after the MMU has been
  turned on.
