intel/genxml: Change 3DSTATE_CONSTANT_XS::MOCS to be MBZ on Gfx8.

Browse Source 
The Broadwell PRM says: "Constant Buffer Object Control State must
always be programmed to zero."

This patch changes the MOCS field in gen8.xml to be "mbz" type, so that
it's impossible to set it to a non-zero value.
