        src/sys/arch/m68k/m68k: pmap_68k.c

Log Message:
- pte_set() and pte_mask() are only used for HP MMU VAC shenanigans; only
  make them available if MMU_CONFIG_HP_CLASS is true.  Also, don't bother
  with the inline asm; it's not really needed at all.
- Don't use atomic_add_ulong() for pmap_stat_update(), as it is implemented
  in terms of CAS, which must be avoided on __HAVE_M68K_BROKEN_RMC systems.
  It's only used inside pmap critical sections, so just garden-variety C
  arithmetic is fine.
- pmap_reference() / pmap_destroy() get similar treatment -- avoid
  atomic_inc and atomic_dec.  In this case, wrap the arithmentic inside
  PMAP_CRIT_ENTER() / PMAP_CRIT_EXIT().
