fbdev: add new framebuffer driver for Fujitsu MB862xx GDCs 



Add a framebuffer driver for the Fujitsu Carmine/Coral-P(A)/Lime graphics
controllers.  Lime GDC support is known to work on PPC440EPx based lwmon5
and MPC8544E based socrates embedded boards, both equipped with Lime GDC.
Carmine/Coral-P PCI GDC support is known to work on PPC440EPx based
Sequoia board and also on x86 platform.
