 Log Message:
 hack around PR#38480:
 
 - rename MTRR_I686_NVAR to MTRR_I686_NVAR_MAX, still set to 8
 - store mtrr VCNT value into i686_mtrr_vcnt.  if it is less than 8,
   zero out the relevant parts of mtrr_raw[].msraddr
 - replace all usage of MTRR_I686_NVAR with either i686_mtrr_vcnt or
   with MTRR_I686_NVAR_MAX as appropriate
 - in i686_mtrr_reload() and mtrr_init_first() don't use mtrr_raw[]
   addresses of 0
 
 still needs a bunch of reworking to handle VCNT > 8 case.
