drm/i915/psr: Make idle_frames sensible again
There are panels that needs 4 idle frames before entering PSR,
but VBT is unproperly set.
Also lately it was identified that idle frame count calculated at HW
can be off by 1, what makes the minimum of 2, at least.
Without the current vbt+1 we are with the risk of having HW calculating
0 idle frames and entering PSR when it shouldn't. Regardless the lack
of link training.
[Jani: there is some disagreement on the explanation, but the commit
regresses so revert it is.]

We get 1 warning when building kernel with W=1:
drivers/gpu/drm/vc4/vc4_bo.c:147:6: warning: no previous prototype for 'vc4_bo_cache_purge' [-Wmissing-prototypes]
In fact, this function is only used in the file in which it is
declared and don't need a declaration, but can be made static.
So this patch marks it 'static'.

drm/nouveau/acpi: use DSM if bridge does not support D3cold

Even if PR3 support is available on the bridge, it will not be used if
the PCI layer considers it unavailable (i.e. on all laptops from 2013
and 2014). Ensure that this condition is checked to allow a fallback to
the Optimus DSM for device poweroff.
Initially I wanted to call pci_d3cold_enable before checking bridge_d3
(in case the user changed d3cold_allowed), but that is such an unlikely
case and likely fragile anyway. The current patch is suggested by Mika

Of course, the plane itself should be disabled as well.

mode change and disabling-enabling plane in plane's ->atomic_update
