The suspend_freq is a fixed value for devfreq core, while the
resume_freq will be changed dynamically based on the last previous
updated frequency value of the device.
When device is put into suspend mode, devfreq core will update the
resume frequency with the suspend frequency. Therefore, when the device
is resumed back again, it will run at suspend_freq.
Forcelly set the suspend_freq as Fmax so that device will run at Fmax
when it is resumed back.

The original resume_freq will be overridden when the device is put
into suspend mode. Therefore, the resume cycle won't always use the
max frequency of the device to set the actmon count weight.
Change the implementation to use scaling_max_freq to always use the
max frequency of the device to set the actmon count weight.

Method invocation for updating count weight for nvdec may conflict
with a job being submitted through host1x.
Change the implementation to set count weight values for both actmon and
the engine once in runtime resume cycle to prevent possible conflicts.

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.

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.

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.

Implement the get_streamid_offset and can_use_memory_ctx callbacks
required for supporting context isolation. Since old firmware on VIC
cannot support context isolation without hacks that we don't want to
implement, check the firmware binary to see if context isolation
should be enabled.

NVDEC's TRANSCFG register is at a different offset than VIC.
This becomes a problem now when context isolation is enabled and
the reset value of the register is no longer sufficient.
