sh: r2d - add lcd planel timings to sm501 platform data

This patch adds timings to drive a Sharp LQ104V1DG21 lcd panel that can
be hooked up to R2D-1 or R2D-PLUS. The sm501fb driver should leave the
pins FPEN and VBIASEN alone, and this patch instructs the driver to do
so by not setting flags flags for these pins.

This patch works best together with the patch posted to the
linux-fbdev-devel list "sm501fb: control panel pin usage with platform
data flags", but this patch can be merged independently.
