Move runtime PM management of older UAPI code paths into the common place.
This removes boilerplate code from client drivers.

drm/tegra: nvdec: Stop channel on suspend2021-12-16T13:07:08ZDmitry Osipenkodigetx@gmail.com2021-11-30T23:23:23Zurn:sha1:28b16229dbf15b3dbbbc5247ac1c514b373964d3
CDMA must be stopped before hardware is suspended. Add channel stopping
to RPM suspend callback. Add system level suspend-resume callbacks.
Runtime PM initialization is moved to host1x client init phase because
RPM callback now uses host1x channel that is available only when host1x
client is registered.

drm/tegra: Mark nvdec PM functions as __maybe_unused2021-12-16T13:07:07ZArnd Bergmannarnd@arndb.de2021-10-13T14:41:36Zurn:sha1:e1189fafa5a1c49407a1bc01d850cc6dd52c058d
The resume helper is called conditionally and causes a harmless warning
when stubbed out:
drivers/gpu/drm/tegra/nvdec.c:240:12: error: 'nvdec_runtime_resume' defined but not used [-Werror=unused-function]
240 | static int nvdec_runtime_resume(struct device *dev)
Mark both suspend and resume as __maybe_unused for consistency to avoid
this warning.

drm/tegra: Mark nvdec_writel() as inline2021-12-16T13:07:07ZArnd Bergmannarnd@arndb.de2021-10-13T14:40:58Zurn:sha1:2245c2a2722be04ed15012d169a7ceb7df7550a7
Without CONFIG_IOMMU_API, the nvdec_writel() function is unused, causing
a warning:
drivers/gpu/drm/tegra/nvdec.c:48:13: error: 'nvdec_writel' defined but not used [-Werror=unused-function]
48 | static void nvdec_writel(struct nvdec *nvdec, u32 value, unsigned int offset)
| ^~~~~~~~~~~~
As this is a trivial wrapper around an inline function, mark it as
inline itself, which avoids the warning as well.

drm/tegra: Bump VIC/NVDEC clock rates to Fmax2021-12-16T13:07:06ZMikko Perttunenmperttunen@nvidia.com2021-09-16T15:09:20Zurn:sha1:e97a951f194c218aaec34631dca40fcb0c85f309
To get full performance out of these engines, bump their clock rates
to maximum. In the future we may want something smarter but this
should be fine for now.

Add support for booting and using NVDEC on Tegra210, Tegra186
and Tegra194 to the Host1x and TegraDRM drivers. Booting in
secure mode is not currently supported.
