Per commit 2e586a7e01 "drm/vmwgfx: Map the fifo as cached" the driver
expects the fifo registers to be cacheable. In preparation for
deprecating ioremap_cache() convert its usage in vmwgfx to memremap().

I'm getting unclaimed register writes when checking the WM registers
after the crtc is disabled. So I would imagine those are guarded by
the crtc power well. Fix this by not reading out wm state when the

syncpoints are resources provided by host1x and their lifetime is tied
to the host1x device. They are not properly reference counted either, so
removing the host1x device before any of its clients causes a use-after-
free error. Adding proper reference counting would be a major enterprise
so work around it for now by requesting and freeing the syncpoint at
init and exit time, respectively. The host1x device is guaranteed to be
around at this point.

This worked before the dw-hdmi bridge code was changed to validate
the setup data more strictly. Add back support for modes with a
pixel clock up to 216MHz. Even higher clocks should work, but we
are missing the required setup data for now.
Also change the mode validate callbacks to disallow modes with
higher pixelclocks, so we don't end up failing the modeset later
on.

Kabylake is a Intel® Processor containing Intel® HD Graphics
following Skylake.
It is Gen9p5, so it inherits everything from Skylake.
Let's start by adding the platform separated from Skylake
but reusing most of all features, functions etc. Later we
rebase the PCI-ID patch without is_skylake=1
so we don't replace what original Author did there.
Few IS_SKYLAKEs if statements are not being covered by this patch
on purpose:
- Workarounds: Kabylake is derivated from Skylake H0 so no
W/As apply here.
- GuC: A following patch removes Kabylake support with an
explanation: No firmware available yet.
- DMC/CSR: Done in a separated patch since we need to be carefull
and load the version for revision 7 since
Kabylake is Skylake H0.

with rapid ringbuffer wraparound) the amount of available space
on each ringbuffer upon reset is less than when we start. Do one
more pass over all the ringbuffers to reset the available space
