Now there are no users of the return value of the drm_panel_prepare(),
drm_panel_unprepare(), drm_panel_enable() and drm_panel_disable() calls.
Usually these calls are performed from the atomic callbacks, where it is
impossible to return an error. Stop returning error codes and return
void instead.

Refactor the driver to add support for the powkiddy,rk2023-panel
panel. This panel is extremely similar to the rg353p-panel but
requires a smaller vertical back porch and isn't as tolerant of
higher speeds. Note that while all of these panels are identical in
size (70x57) it is possible future panels may not be.
Tested on my RG351V, RG353P, RG353V, and RK2023.

Add support for the Anbernic 351V. Just like the 353 series the
underlying vendor is unknown/unmarked (at least not visible in a
non-destructive manner). The panel had slightly different init
sequences and timings in the BSP kernel, but works fine with the
same ones used in the existing driver. The panel will not work without
the inclusion of the MIPI_DSI_CLOCK_NON_CONTINUOUS flag, and this flag
prevents the 353 series from working correctly, so a new compatible
string is added.
Tested colors and timings using modetest and all seem to work identical
to the 353 otherwise.

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.

Support NewVision NV3051D panels as found on the Anbernic RG353P and
RG353V. The underlying LCD part number for the RG353x devices is
unknown, so the device name and a fallback for the driver IC is
used instead.
