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.
Name the device tree compatible after the panel model according to
iFixit.
