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.
