79abca2b39 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.

0f3b68b66a drm/dsi: Add _NO_ to MIPI_DSI_* flags disabling features
Many of the DSI flags have names opposite to their actual effects,
e.g. MIPI_DSI_MODE_EOT_PACKET means that EoT packets will actually
be disabled. Fix this by including _NO_ in the flag names, e.g.
MIPI_DSI_MODE_NO_EOT_PACKET.

with the Khadas Edge-V, Captain, VIM3 and VIM3L Single Board Computers.
It provides a MIPI DSI interface to the host, a built-in LED backlight
