[PATCH] Remove xcalibrate and tslib support

[Abdoulaye Walsimou Gaye]

Please don't do that.
I use Kdrive (Xfbdev) with tslib.
Xfbdev + tslib is extremely useful for embedded systems without
keyboard, which are driven
by a pen. This is the case for many new smart phones for example.
So please, don't do that.
Thanks,
AWG
