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