Input: tsdev - schedule removal



Compaq touchscreen emulation (drivers/input/tsdev.c) is old,
was obsolete when it was written by the authors own admission
and much better userspace solutions like tslib now exist.
The name is also confusing.

		Why: The code says it was obsolete when it was written in 2001.
		tslib is a userspace library which does anything tsdev can do and

		The name "tsdev" is also extremely confusing and lots of people have
