Currently calling venus_helper_buffers_done() will return buffers to
user for both capture and output queues in the same call. This is
wrong because both queues are really separate and calling
stop_streaming on one queue shouldn't return buffers for the other.
Solve this by add a new queue type argument and fix the clients of
the helper function.

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.

Redesign core (vcodec) clock control to give the venus core more
freedom to control them in order to make possible to use core

Move all clock and pmdomain functions in separate file and abstract

This is implementing multi-stream decoder support. The multi-stream
will be used to enable/disable the primary/secondary decoder
outputs. Depending on formats on both decoder outputs we could
implement downscale, dithering and supporting UBWC (universal
bandwidth compression) formats. The UBWC compressed raw format is
used to optimize interconnect bandwidth for bigger resolutions
like 4K and hence we will get some power-saving benefits as well.
Both decoder outputs are distinguished by buffer_type field in
the HFI packets. For example HFI_BUFFER_OUTPUT is the buffer type
for primary decoder output and HFI_BUFFER_OUTPUT2 is for secondary
decoder output.
Starting from Venus 4xx the DPB buffers format must be UBWC, so
the multi-stream becomes mandatory for this Venus version. That
means that we need to allocate internally in the driver a set of
DPB buffers (with UBWC NV12 format) and give them to the firmware.
The other decoder output (we called it OPB) format will be NV12
linear format and with the same resolution (or smaller in case
the user wants to downscale).
The DPB buffers are used for decoder reference frames and those
have to be in a specific format (UBWC). So one decoder output is
used to fill those reference buffers while the other output is
used to fill the userspace buffers with the user requested format.

* core.c has implemented the platform driver methods, file
operations and v4l2 registration.
* helpers.c has implemented common helper functions for:
- buffer management
- vb2_ops and functions for format propagation,
- functions for allocating and freeing buffers for
internal usage. The buffer parameters describing internal
buffers depends on current format, resolution and codec.
- functions for calculation of current load of the
hardware. Depending on the count of instances and
resolutions it selects the best clock rate for the video
core.
