drm/panel: ltk050h3146w: use dev_err_probe wherever possible
...
This is only a cosmetic change.
This replaces a hand-crafted EPROBE_DEFER handling for deciding to print
an error message with dev_err_probe.
A side-effect is that dev_err_probe also adds a debug message when it's
not EPROBE_DEFER, but this is seen as an improvement.

drm/panel: ltk050h3146w: only print message when GPIO getting is not EPROBE_DEFER
...
devm_gpiod_get_optional may return EPROBE_DEFER in case the GPIO
controller isn't yet probed when the panel driver is being probed.
In that case, a spurious and confusing error message about not being
able to get the reset GPIO is printed even though later on the device
actually manages to get probed.
Use dev_err_probe instead so that the message is only printed when it
truly matters.

The ltk050h3148w variant expects the horizontal component lane byte clock

Using the pixel clock rate by default for this calculation was introduced

its init sequence, mode details and mode flags.

currently hardcoded mode flags to the .data field of of_device_id

drm: Explicitly include correct DT includes
...
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

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.

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.

drm/panel: use mipi_dsi_dcs_write_buffer where possible
...
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.
