Since devm_of_icc_get is used, no need to call icc_put when device probe
fails or device driver is removed.

9f2ed528c8 drm/tegra: Fix interconnect support for Linux v6.2+ 
Interconnect support for multimedia engines is disable for Linux v6.2
kernels. Rather than always disabling interconnect support for these
kernels, we just need to ensure the necessary upstream kernel patches
are in place for Linux v6.2 kernels. Therefore, enable interconnect
support for all kernels.

3264c9dfca drm/tegra: Skip non-clock update in suspend mode 
When the device is in suspend mode, There is no point to update
actmon count weight and send ICC request for the device.

If ICC request is sent for the device in suspend mode, in osidle state,
the default EMC frequency will be affected due to the accumulated ICC
bandwidth QoS constraint, and affect the overall osidle power.

5ad064a2bb drm/tegra: Enable runtime PM during probe for internal engines 
Currently, engine drivers only enable runtime PM during the host1x
init callback. This can happen slightly later than the probe, which
can cause the power domain to intermittently not be turned off after
probe.

My hypothesis is that there is a race condition between the post-probe
power domain poweroff that is done from a queued work, and the
pm_runtime_enable call happening in the host1x init callback.
If the pm_runtime_enable call happens first, everything is OK and
the power off work can disable the power domain as PM runtime is
enabled and the device is runtime suspended. If power off work runs
first, PM runtime is still disabled for the device and the domain
must be kept powered.

Resolve the issue by moving the runtime PM enablement to the
probe function.
