drm/tegra: Preparatory work for v5.19

This contains a single patch from a series that's ready to go for v5.10
but is also a shared build-time dependency for an IOMMU series that is
planned for v5.20. The idea is to take this into v5.19 to fulfill that
dependency and remove the need for close coordination for the two
series.

drm/tegra: Changes for v5.19-rc1

Only a few fixes this time, and some debuggability improvements.

drm/tegra: Changes for v5.18-rc1

This contains a couple more minor fixes that didn't seem urgent enough
for v5.17. On top of that this improves YUV format support on older
chips.

drm/tegra: Fixes for v5.17-rc6

Contains a couple of fixes for Tegra186 suspend/resume, syncpoint
waiting, a build warning and eDP on older Tegra devices.

drm/tegra: Changes for v5.17-rc1

This contains a fairly large rework that makes the buffer objects behave
more according to what the DMA-BUF infrastructure expects. A buffer
object cache is implemented on top of that to make certain operations
such as page-flipping more efficient by avoiding needless map/unmap
operations. This in turn is useful to implement asynchronous commits to
support legacy cursor updates.

Another fairly big addition is the NVDEC driver. This uses the updated
UABI introduced in v5.15-rc1 to provide access to the video decode
engines found on Tegra210 and later.

This also includes some power management improvements that are useful on
older devices in particular because they, together with a bunch of other
changes across the kernel, allow the system to scale down frequency and
voltages when mostly idle and prevent these devices from becoming
excessively hot.

The remainder of these changes is an assortment of cleanups and minor
fixes.
