this add functions for:
- remove buffers from src/dst queue by index
- remove exact buffer from src/dst queue
also extends m2m API to iterate over a list of src/dst buffers
in safely and non-safely manner.

Changes since previous v5:
* dropped rproc phandle (remoteproc is not used anymore)
* added subnodes paragraph with descrition of three subnodes:
- video-decoder and video-encoder - describes decoder (core0) and
encoder (core1) power-domains and clocks (applicable for msm8996
Venus core).
- video-firmware - needed to get reserved memory region where the
firmware is stored.

* core.c has implemented the platform dirver 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.

Rather than operating on a global variable I think you should either
return your firmware_mem pointer or the device pointer to the caller of
venus_boot() and have the core pass that back into venus_shutdown().

This should not be necessary.
Further more, if it's already initialized it's safe to assume that the
allocation below will fail - regardless of you clearing it or not.

As this should follow the life of dev you can use dmam_alloc_coherent()
to reduce the clean up paths.

If you use dmam_alloc_coherent() this goes.

And I would suggest that as this is related to the device you should
release it in the dev->release function; turning this function into
device_unregister(&fw->dev).
(The devres allocation will be freed right before the release function
is called)

You can skip this this check, as qcom_mdt_load() will fail if any part
of the firmware doesn't fit - and we would benefit from making that
error message more verbose.

This is not only the error path, so "release_fw" would be better.

I will take your comments and will pass struct device *fw_dev as an
argument of venus_boot. Also I will move memory allocation in venus_boot
and by that way I don't need to keep memory attributes from above structure.

This is the implementation of HFI. It is charged with the
responsibility to comunicate with the firmware through an
interface commands and messages.
- hfi.c has interface functions used by the core, decoder
and encoder parts to comunicate with the firmware. For example
there are functions for session and core initialisation.
- hfi_cmds has packetization operations which preparing
packets to be send from host to firmware.
- hfi_msgs takes care of messages sent from firmware to the
host.

Here is the implementation of Venus video accelerator low-level
functionality. It contanins code which setup the registers and
startup uthe processor, allocate and manipulates with the shared
memory used for sending commands and receiving messages.
