[Intel-gfx] [PATCH 0/2] Apply BDW workarounds using LRIs in render init fn

[Arun Siluvery]

Workarounds for BDW are applied using LRIs during render ring initialization.
Only those WA registers that are part of register state are initialized
in this fn, remaining 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.
