[PATCH] SharpSL: Add cxx00 support to the Corgi LCD driver

The same LCD is present on both the Sharp Zaurus c7x0 series and the cxx00 but
with different framebuffer drivers (w100fb vs.  pxafb).  This patch adds
support for the cxx00 series to the LCD driver.  It also adds some LCD to
touchscreen interface logic needed by the touchscreen driver to prevent
interference problems, the idea being to keep all the ugly code in one place
leaving the drivers themselves clean.  sharpsl.h is used to provide the
abstraction.
