drm/mipi-dsi: Make remove callback return void
...
All implementations return 0 and the return value of mipi_dsi_drv_remove()
is ignored anyhow.
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour.

...
The panel uses the same driver IC and has the same resolution but a
slightly different default mode. It seems it can work with the same
init sequence.

We've seen some (non permanent) burn in and bad white balance
on some of the panels. Adding this bit from a vendor supplied
sequence fixes it.

drm/panel: mantix: Fix panel reset
...
The mantix panel needs two reset lines (RESX and TP_RSTN) deasserted to
output an image. Only deasserting RESX is not enough and the display
will stay blank. Deassert in prepare() and assert in unprepare() to keep
device held in reset when off.
