Richard Purdie 41b1bce80b [PATCH] w100fb: Update corgi platform code to match new driver 
This patch moves the platform specific Sharp SL-C7x0 LCD code from the
w100fb driver into a more appropriate place and updates the Corgi code to
match the new w100fb driver.

It also updates the corgi touchscreen code to match the new simplified
interface available from w100fb.
