In the case where we have a back-to-back submission that shares the same
BO, this BO will be prematurely moved to inactive_list while retiring the
first submit. But it will be still part of the second submit which is
being processed by the GPU. Now, if the shrinker happens to be triggered at
this point, it will result in a premature purging of this BO.
To fix this, we need to refcount BO while doing submit and retire. Then,
it should be moved to inactive list when this refcount becomes 0.

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

previously enabled. Fix it.

The vc4 display engine has a first controller called the HVS that will
perform the composition of the planes. That HVS has 3 FIFOs and can
therefore compose planes for up to three outputs. The timings part is
generated through a component called the Pixel Valve, and the BCM2711 has 6
of them.
Thus, the HVS has some bits to control which FIFO gets output to which
Pixel Valve. The current code supports that muxing by looking at all the
CRTCs in a new DRM atomic state in atomic_check, and given the set of
constraints that we have, assigns FIFOs to CRTCs or reject the mode
entirely. The actual muxing will occur during atomic_commit.
However, that doesn't work if only a fraction of the CRTCs' state is
updated in that state, since it will ignore the CRTCs that are kept running
unmodified, and will thus unassign its associated FIFO, and later disable
it.
In order to make the code work as expected, let's pull the CRTC state of
all the enabled CRTC in our atomic_check so that we can operate on all the
running CRTCs, no matter whether they are affected by the new state or not.
