qualcomm/sc7180: Switch to common MIPI panel library

This patch changes the sc7180 boards to use the new common MIPI panel
framework, which allows more flexible initialization command packing and
sharing panel definitions between boards. (I'm taking the lane count
control back out again for now, since it seems we only ever want 4 for
now anyway, and if we ever have a need for a different lane count it's
not clear whether that should be a property of the board or the panel or
both. Better to leave that decision until we have a real use case.)

Also, the code was not written to deal with DCS commands that were not a
length divisible by 4 (it would read over the end of the command
buffer). The corresponding kernel driver seems to pad the command with
0xff instead, let's do the same here.
