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

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.

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.

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.

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.
