[PATCH] fb: SM501 framebuffer driver

Driver for the Silicon Motion SM501 multifunction device framebuffer
subsystem.

This driver supports both the CRT and LCD panel heads, with some simple
acceleration for the cursor plotting and support for screen panning.  There
is no current support for bitblt/drawing engines, which should be added at
a later date.

This has been tested on a number of configurations, including PCI and
generic-bus, on PPC, ARM and SH4
