The controller chip of Feixin K101-IM2BA02 is going to be discontinued,
so Feixin start to provide K101-IM2BYL02 panel as a replacement, which
utilizes Ilitek ILI9881C controller.
Add support for K101-IM2BYL02 panel.
By the way, is there a way that can try both kind of panels in the same
kernel/DTB combo? K101-IM2BYL02 has the same pinout with K101-IM2BA02,
and PineTab schedule to switch to it w/o modifying the mainboard.
