The FMT blocks control how data is sent from the backend
of the display pipe to to monitor.  Proper set up of the
FMT blocks are required for 30bpp formats.  Additionally,
dithering can be enabled on for better display with 18 and
24bpp displays.  The exception is LVDS/eDP which atom
takes care of in the SelectCRTC_Source table.  For now
just enable truncation until we test dithering more.

The internal cp interrupts need to be enabled and
disabled at specific times in order clockgating to

of the CP_INT_CNTL register to respect the current
state of the internal CP interrupts when making
changes to the other interrupts in CP_INT_CNTL.

The vram scratch buffer needs to be initialized
before the mc is programmed otherwise we program
0 as the GPU address of the default GPU fault
page.  In most cases we put vram at zero anyway and
reserve a page for the legacy vga buffer so in practice
this shouldn't cause any problems, but better to make
it correct.

For powergating, we just need to re-init the registers, there
is no need to restore the uvd BOs.  This just adds needless
work when powergating uvd for playback while the system is
on.  We only need to restore the uvd BOs on an actual resume
from suspend or when the driver loads.

This fixes multi-stream UVD playback on KB systems.

Clockgating requires signalling between the CP and the
RLC to work properly.  Resetting the CP block in the
CP resume code messed up the internal coordination
between the blocks.  Removing the reset allows gfx
clockgating to work properly.  However, when gfx clock
gating is enabled, there is a strange interaction with
dpm which causes the chip to stay in the high performance
level all the time, so leave gfx clockgating disabled
for now.
