The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert the mediatek drm drivers from always returning zero in
the remove callback to the void returning variant.

This patch adds the missing MODULE_DEVICE_TABLE definitions on different
Mediatek drivers which generates correct modalias for automatic loading
when these drivers are compiled as an external module.

This patch adds drivers for the HDMI bridge connected to the DPI0
display subsystem function block, for the HDMI DDC block, and for
the HDMI PHY to support HDMI output.
This includes an interface to the generic hdmi-codec driver to start
or stop audio playback and to retrieve ELD (EDID like data) to limit the
supported audio formats to the HDMI sink capabilities.
