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.
