Subject: [PATCH RFC 01/10] drm/panel: Clean up SOFEF00 config dependencies

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.

Fixes: 5933baa36e26 ("drm/panel/samsung-sofef00: Add panel for OnePlus 6/T devices")
