In the H3 ES2.0 SoC the VSP2-DL instance has two connections to DU
channels that need to be configured independently. Extend the VSP-DU API
with a pipeline index to identify which pipeline the caller wants to
operate on.

The display buffers must be mapped for DMA through the device that
performs memory access. Expose an API to map and unmap memory through
the VSP device to be used by the DU.
As all the buffers allocated by the DU driver are coherent, we can skip
cache handling when mapping and unmapping them. This will need to be
revisited when support for non-coherent buffers will be added to the DU
driver.

To be able to perform page flips in DRM without flicker we need to be
able to notify the rcar-du module when the VSP has completed its
processing.
We must not have bidirectional dependencies on the two components to
maintain support for loadable modules, thus we extend the API to allow
a callback to be registered within the VSP DRM interface.

The interface to configure the LIF in the VSP1 requires adapting the
function prototype for any changes. This makes extending the interface
difficult.
Change the function prototype to pass a structure which can be easily
extended.
This changes the means of disabling the pipeline, by now passing a NULL
configuration rather than passing either a 0 width or height.

The vsp1_du_atomic_update_ext() function takes 7 RPF configuration
parameters, and more will likely be added later. This makes the code
difficult to read and error-prone as multiple parameters have the same
type.
Make the API safer and easier to extend in the future by grouping all
parameters in a structure. Use macro magic to ease the transition to the
new function by allowing the old and new functions to be called using
the same name. The macros and static inline wrapper will be removed as
soon as the caller is updated.

Add two API functions named vsp1_du_atomic_begin() and
vsp1_du_atomic_flush() to signal the start and end of an atomic update.
The vsp1_du_setup_rpf() function is renamed to vsp1_du_atomic_update()
for consistency.
With this new API, the driver will reprogram all modified inputs
atomically before restarting the video stream.
