drm/panel: add samsung s6e3fa7 panel driver

The S6E3FA7 display controller is enabled in every Pixel 3a (non-XL)
variant. Add the driver for it, generated by
linux-mdss-dsi-panel-driver-generator.

There are other panels connected to the same S6E3FA7 display controller,
such as the AMS604NL01 panel, which are incompatible with this driver.
