fb: add support of LCD display controller on pxa168/910 (base layer)

Browse Source 
This driver is originally written by Lennert, modified by Green to be
feature complete,  and ported by Jun Nie and Kevin Liu for pxa168/910
processors.

The patch adds support for the on-chip LCD display controller, it
currently supports the base (graphics) layer only.
