With the latest dynamic selection of the output component, we can now
support different outputs. Move current output component into the
dynamic routes array and add the new DSI0 output.

Please disregard this patch (the others are ok). There must gone something
wrong during my testing. DDP_COMPONENT_MERGE0 won't work with
DDP_COMPONENT_DSI0. If anyone has more insights, I'm all ears.
I was *convinced* that the MERGE0 SOUT was connected to DSI0!!!
...but you're right, here, and thanks for catching that: there's no way to
get MERGE0 connected to DSI0; if you check in the datasheet for VDO_SEL_IN,
you can get data from MERGE0 only for DSI*1*, not 0.
The only way is to connect DSC_WRAP0 (DDP_COMPONENT_DSC0 in mtk_drm_drv btw)
directly to DSI0 (or dither to dsi0)... unless there is a way to change the
pinmux to invert the pins for DSI0/1?
You could assign the DSI1 controller to the one that is currently DSI0 for you.
That would solve the issue here.
Cheers!
Angelo
