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.

The Gen3 RPF includes an alpha multiplier that can both multiply the
alpha channel by a fixed global alpha value, and multiply the pixel
components to convert the input to premultiplied alpha.
As alpha premultiplication is available in the BRU for both Gen2 and
Gen3 we handle it there and use the Gen3 alpha multiplier for global
alpha multiplication only. This prevents conversion to premultiplied
alpha if no BRU is present in the pipeline, that use case will be
implemented later if needed.

The RPF source memory pointers need to be offset to take the crop
rectangle into account. Offsets are computed in the RPF stream start,
which can happen (when using the DRM pipeline) after calling the RPF
.set_memory() operation that programs the buffer addresses.
The .set_memory() operation tries to guard against the problem by
skipping programming of the registers when the module isn't streaming.
This will however only protect the first use of an RPF in a DRM
pipeline, as in all subsequent uses the module streaming flag will be
set and the .set_memory() operation will use potentially incorrect
offsets.
Fix this by allowing the caller to decide whether to program the
hardware immediately or just cache the addresses. While at it refactor
the memory set code and create a new vsp1_rwpf_set_memory() that cache
addresses and calls the .set_memory() operation to apply them to the
hardware.
As a side effect the driver now writes all three DMA address registers
regardless of the number of planes, and initializes unused addresses to
zero.

The datasheet clearly states that all but a few registers can't be
modified when the device is running. Programming the intensity
parameters in the control set handler is thus prohibited. Program it
when starting the module instead.
This requires storing the intensity value internally as the module can
be started from the frame completion interrupt handler, and accessing
control values requires taking a mutex.
