Redesign core (vcodec) clock control to give the venus core more
freedom to control them in order to make possible to use core
selection feature on Venus IP v4.
Move all clock and pmdomain functions in separate file and abstract
power control with common operations per Venus IP version.

From: Aniket Masule <amasule@codeaurora.org>
Presently the core (vcodec pipelines) assignment is static. Here we
introduce dynamic load balancing across the cores depending on the
current session load. The load on earch core is calculated and core
with minimum load is assigned to given instance. This will be
applicable on Venus v4 with more than one vcodec cores.

Those two properties are not implemented for Venus v4 (sdm845),
thus don't set them to firmware.

This event indicate that the source color bit-depth is changed
during run-time. The client must get the new format and re-allocate
buffers for it. This can usually happens with video decoder (encoders)
when the bit-stream color bit-depth is changed from 8 to 10bits
or vice versa.

Handle 10bit video streams in the decoder by using dithering, i.e
the decoder output buffers will be in 8bit format.
The runtime handling is implemented by sending v4l2 event to
userspace application, then the application should stop the
streaming on capture queue and initiate format negotiation, and
start streaming again.

In order to use dynamic video codec assignment add a new sdm845-v2
DT compatible and new venus_resource structure to cover the binding
where all pmdomains and clocks are under the venus_core control.

possible to support dynamic core assignment on v4.

You can have 20 IOMMUs attached to the Venus IP? The binding is for 1
SoC, you should know how many IOMMUs there are.
