It's silly to have if(SKL) checks in gen9_init_clock_gating() when
we can just move those bits into skl_init_clock_gating().
I'm not entirely convinced we even need this w/a, or if we do
then maybe we want it for kbl/cfl as well. IIRC it was only
listed in the wadb, but that is now dead so can't double check
anymore. Bspec doesn't seem to have any purely skl specific
DOP clock gating workarounds listed.

Probably should move this to the gt w/a code actually. But
there's a lot more gt related stuff still in .init_clock_gating()
so should grab a bigger shovel to move it all in one go.

WAC6entrylatency is trying to fix excessive rc6 entry latency caused
by the extra delay from FBC_LLC_READ_CTRL, which is there for some
extra sync with uncore for frame buffer caching in LLC.
Reading through the hsd the recommendation was to set the FBC_LLC_FULLY_OPEN
bit to disable this extra delay entirely. This can be done whenever fb LLC
caching is not used. The alternative suggestion was to reduce the delay to
eg. 0x5 via updated BIOS programming instructions. But all the kbl/cfl
machines I've seen still have the default 0xff programmed. As we never use
fb LLC caching let's just apply the w/a to all skl derivatives to get
consistent rc6 latencies.
I was able to measure the effect of FBC_LLC_READ_CTRL to rc6 latency
via forcewake. Here's a graph of some of the results:

+----------------------------------------------------------------+
0ms 10ms 20ms 30ms 40ms 50ms 60ms
sleep duration
The default FBC_LLC_READ_CTRL value of 0xff is documented to give us
a 170usec delay. That tracks well with the knees at 0xffff->~44usec and
0x8000->~22usec we see in the graph.
We can see that if we sleep longer than the FBC_LLC_READ_CTRL delay
we always observe the full (~145usec) rc6 wakeup latency. But if we sleep
for less than the FBC_LLC_READ_CTRL delay we see a quicker fw wakeup,
presumably due the hardware not having yet entered rc6 fully.
The other plateaus in the graph I suspect correspond to some shallower
internal rc states.

Those should obviously say msec instead of usec.

Ah, is that what it means by 'must not be set unless coordinated with
uncore?' Ok.

Hmm, so by setting LLC as fully open, there is always a fixed 140us
latency for rc6, implying that we always immediately try to enter rc6
rather than after ~50ms.
I realize that my rc6 power measurements should be with the display
already off and so will not show any effect. :|
The graph does imply that there should be a noticeable effect for
composited desktops, both in power saving and a latency penalty. 140us
is about the same sort of ballpark as all the over startup costs, and
one hopes they overlap.
