Log Message:
Pull up following revision(s) (requested by sborrill in ticket #1173):
        sys/arch/x86/include/mtrr.h: revision 1.4
        sys/arch/x86/x86/mtrr_i686.c: revision 1.18
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.
