The IMG VXD Video Decoder uses the IMG D5520 to provide video
decoding for various codecs including H.264 and HEVC.
Scaling and rotation are also supported by the hardware
and driver. The driver also supports multiple simultaneous
video decodes.

Each mem2mem context is a single stream decode session.
Each session creates it's own vxd context and associated
mem mgr and mmu contexts. Firmware loading, firmware messaging,
and hardware power management (reset) are supported, as well as MMU
programming of the HW.

This patch adds the framework for the v4l2 IMG VXD video decoder
driver, supporting HW initialization, MMU mapping and buffer management.
The decoding functionality is not yet implemented.

The vxd helper provides the functionality for firmware blob preparation
and loading, power management (core reset, etc.), firmware messaging,
interrupt handling, managing the hardware status, and error handling.

The vxd helper also interacts with the memory manager helper to create
a context for each stream and associate it with the mmu context. The
common mappings are done during this creation for the firmware and
rendec buffers.

The memory manager helper library provides functions for managing
the memory context of a decode stream. Each stream will have it's
own memory context with associated mmu context and heap
allocations. The memory manager tracks the allocations and mappings
per context, as well as providing a wrapper around the MMU library.
It also provides functions for the driver to query information about
the page table directory for a particular memory context.

In addition, the memory manager provides the ability to plug in

different heaps (unified, carveout, dmabuf, etc.) that the caller
can use when doing memory allocations.

By default, the "unified" heap functionality is supported. No other
types of heaps are supported at this time, though the framework is
present to add more heap types in the future, if needed. This
heap is used only for allocating internal buffers used for communication
with the hardware, and for loading the firmware.

Functions are provided for creating/destroying a memory context,
creating/destroying an MMU context, mapping and unmapping buffers in
the device MMU, allocating and freeing buffers from specified available
heaps, and retrieving information about those allocations.

The IMG D5520 has an MMU which needs to be programmed with all
memory which it needs access to. This includes input buffers,
output buffers and parameter buffers for each decode instance,
as well as common buffers for firmware, etc.

Functions are provided for creating MMU directories (each stream
will have it's own MMU context), retrieving the directory page,
and mapping/unmapping a buffer into the MMU for a specific MMU context.

Also helper(s) are provided for querying the capabilities of the MMU.
