arch/x86: drivers/display: add framebuffer driver w/ multiboot support

Browse source 
A basic display driver is added for a generic 32-bpp framebuffer.
Glue logic is added to the x86 arch to request the intitialization
of a linear framebuffer by the Multiboot loader (GRUB) and connect
it to this generic driver.
