There is a macro for this already in the <drm/drm_mipi_dsi.h> header, use
that instead and delete the custom DSI write macro defined in the driver.

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.

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.

Update the panel to allow setting the rotation value in device tree.
Tested on an Odroid Go Advance, where the panel is by default rotated 270
degrees.

The panel is able to work when dsi clock is non-continuous, thus
the system power consumption can be reduced using such feature.
Add MIPI_DSI_CLOCK_NON_CONTINUOUS to panel's mode_flags.
Also the flag actually becomes necessary after
commit c6d94e37bdbb ("drm/bridge/synopsys: dsi: add support for non-continuous HS clock")
and without it the panel only emits stripes instead of output.

A few of the new panels create a local macro wrapping around
mipi_dsi_dcs_write. At the same time, they don't really care about the
command/payload split.
mipi_dsi_dcs_write does a kmalloc/memcpy/kfree for payload > 7 bytes.
Avoid that all together by using the _buffer function.
Aside:
panel-xinpeng-xpp055c272.c calls its wrapper "generic" although it
should be "dcs". But that for another day/patch.

Get rid of mode->vrefresh and just calculate it on demand. Saves
a bit of space and avoids the cached value getting out of sync
with reality.
Mostly done with cocci, with the following manual fixups:
- Remove the now empty loop in drm_helper_probe_single_connector_modes()
- Fix __MODE() macro in ch7006_mode.c
- Fix DRM_MODE_ARG() macro in drm_modes.h
- Remove leftover comment from samsung_s6d16d0_mode
- Drop the TODO

Panel driver for the KD35T133 display from Elida, used for example
in the rk3326-based Odroid Go Advance handheld.
changes in v3:
- add missing return value assignment (Francesco)
- re-sort header includes (Sam)
changes in v2:
- rename dsi_generic_write_seq macro to dsi_dcs_write_seq to honor
the underlying mipi_dsi_dcs_write (Robin)
