Kristoffer Ericson 3ed167af96 fbdev: s1d13xxxfb: add accelerated bitblt functions 
Add accelerated bitblt functions to s1d13xxx based video chipsets, more
specificly functions copyarea and fillrect.

It has only been tested and activated for 13506 chipsets but is expected
to work for the majority of s1d13xxx based chips.  This patch also cleans
up the driver with respect of whitespaces and other formatting issues.  We
update the current status comments.
