We call platform_get_drvdata() in tps6507x_ts_remove(),
thus we should call platform_set_drvdata() in tps6507x_ts_probe().

Stanse found that tsc is dereferenced earlier than checked for being
NULL in tps6507x_ts_remove. Remove the test because there is no way
for tsc to be NULL there.

1) Use msecs_to_jiffies() instead of calculating by hand.
2) Call cancel_delayed_work_sync() instead of cancel_delayed_work()
   followed by a separate flush_workqueue().
3) Remove the "tsc->wq = 0;"  Sparse complains about that because
   tsc->wq is a pointer, not an int.  It's not needed because we just
   free the pointer anyway.

Add touch screen input driver for TPS6507x family of multi-function
chips.  Uses the TPS6507x MFD driver.  No interrupt support due to
testing limitations of current hardware.
