Add CPU fallback for G2D
This adds a CPU fallback for G2D using pixman (www.pixman.org)
for 2D filling and blitting actions in case of missing
G2D mixer processor on devices != A10/A20.
The software fallback is one of the requirements for OSD support
on Allwinner devices other than A10/A20.
Note: Pixman expects pixel data as premultiplied alpha values, so
you have to ensure, that your application uses the correct values.
