Input: gpio_tilt - delete driver
This driver was merged in 2011 as a tool for detecting the orientation of a screen. The device driver assumes board file setup using the platform data from <linux/input/gpio_tilt.h>. But no boards in the kernel tree defines this platform data. As I am faced with refactoring drivers to use GPIO descriptors and pass decriptor tables from boards, or use the device tree device drivers like these creates a serious problem: I cannot fix them and cannot test them, not even compile-test them with a system actually using it (no in-tree boardfile). I suggest to delete this driver and rewrite it using device tree if it is still in use on actively maintained systems. I can also offer to rewrite it out of the blue using device tree if someone promise to test it and help me iterate it.
