[Intel-gfx] [PATCH 2/3] drm/i915: put ring frequency and turbo setup into a work queue v2

[Rodrigo Vivi]

I was here trying to cheking init values and change forcewake set
during init, etc and nothing was getting RC6 running after resume
besides that msleep(50) workaround after setting CACHE_MODE_0...

Now with your patch my RC6 is back to life after resume: RC6 35.8% :D

Well, but when looking at BSPec I noticed that CACHE_MODE_0 is 0x02120
only for SNB. For IVB+ is 0x7004 what is defined as CACHE_MODE_1 in
our code.
I'm afraid we are doing something wrong here.... or am I missing something?
