drm/panel: Clean up S6E3HA2 config dependencies and fill help text

As per the config name this Display IC features a DSI command-mode
interface (or the command to switch to video mode is not
known/documented) and does not use any of the video-mode helper
utilities, hence should not select VIDEOMODE_HELPERS. In addition it
uses devm_gpiod_get() and related functions from GPIOLIB.
