[Intel-gfx] [RFC] Add BDW workarounds to golden render state

[arun.siluvery at linux.intel.com]

From: Arun Siluvery <arun.siluvery at linux.intel.com>

In this patch workarounds for BDW are applied to golden render state.
Only those registers that are part of register state are added to this batch.
Remaining workarounds are still in its current place init_clock_gating() which
are not affected by a gpu reset. I can send another patch where they can be
moved to render ring init function but during testing I found their state
doesn't change after reset, please give your comments on this.
