Add support for using a single layer mixer to drive two video

Fix stride corruption issue due to panel portswap observed when
some video layers cross panel split boundaries. Fix is to
initialize panel with the imgswap feature enabled, and then
modify the DSI CTRL horizontal tiling mapping to undo the swap.

Update the way in which the virtual encoder requests the physical
encoder enables so that the master physical encoder is always
enabled last. This is done so that all of the slaves are fully
prepared when the master is enabled, and also allows the master
to update any necessary configuration during its enable callback.

During device probe virtual crtcs are created with no hardware attached.
Color processing(cp) properties can be attached to the virtual crtc by
looking at the hardware catalog. If user-space client sets property cp
driver will check if hardware has been allocated for crtc. If there is
no hardware allocated it will return error for set property

Modify the way that the waiting for previous kickoffs is handled
for the command encoder case. Instead of doing waiting in the
virtual encoder, do the waiting in the command encoder directly.
That way we can check whether we have missed the IRQ. Also
allows waiting for idle before disabling the encoder.

This change adds a debugfs node to enable the misr
crc generation in batch mode. Once this is enabled,
driver will collect the crc numbers during each of
the interfaces interrupt.
To enable/disable the crc generation, respectively:
echo 1 16 > /d/dri0/encoder18/misr_data
echo 0 16 > /d/dri0/encoder18/misr_data
Inputs here represents enable and number of frame in batch.
Maximum batch size supported is 16.
To collect the crc data generated:
