drm: rcar-du: Fix crash when enabling a non-visible plane

The DU driver handles non-visible planes (fully clipped by the display's
boundaries) by considering them as disabled. It thus disables the plane
at the hardware level when the plane is moved off-screen. However, if
the plane was previously disabled and is non-visible when it gets
enabled, the attempt to disable it crashes, as the plane wasn't
previously enabled. Fix it.

hardware as fully present, except we just don't register any
outputs. That's still rather sketchy if the outputs are already
enabled when the driver is loaded. I think the simplest solution
would be to probe everything as normal and just return
disconnected" from all .detect() hooks. That would avoid anything
automagically enabling those outputs, but the driver could then
shut things down using the normal codepaths.

drm/i915: Use fb->format->is_yuv for the g4x+ sprite RGB vs. YUV check

g4x+ sprites have an extra cdclk limitation listed for RGB formats.
For some random reason I chose to use cpp>=4 as the check for that.
While that does actually work let's deobfuscate it by checking
for !is_yuv instead. I suspect is_yuv didn't exist way back when
I originally write the code.

Also drop the duplicate comment.

drm/i915: Fix g4x+ sprite dotclock limit for upscaling

Even if we're not doing downscaling we should account for
some of the extra dotclock limitations for g4x+ sprites. In
particular we must never exceed the 90% rule, and with RGB
that limits actually drops to 80%.

So instead of bailing out when upscaling let's clamp the
scaling factor appropriately and go through the rest of
calculation normally. By luck we already did the full
calculations for the 1:1 case.

drm/i915: Nuke MI_ARB_STATE save/restore

Originally added in commit 1f84e550a870 ("drm/i915 more registers for
S3 (DSPCLK_GATE_D, CACHE_MODE_0, MI_ARB_STATE)") to fix some underruns.

commit 20f949670f51 ("drm/i915: Disable trickle feed via MI_ARB_STATE
