x86/mtrr: Replace size_or_mask and size_and_mask with a much easier concept

Replace size_or_mask and size_and_mask with the much easier concept of
high reserved bits.

While at it, instead of using constants in the MTRR code, use some new

  [ bp:
   - Drop mtrr_set_mask()
   - Unbreak long lines
   - Move struct mtrr_state_type out of the uapi header as it doesn't
     belong there. It also fixes a HDRTEST breakage "unknown type name ‘bool’"
     as Reported-by: kernel test robot <lkp@intel.com>
   - Massage.
