[PATCH i-g-t] tools/intel_reg: Fix mchbar register write

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

I somehow lost the write part of the mchbar register support.
Add it back so that we can also write mchbar registers without
having to remember the address of the mirror range.
