The fbdev emulation currently uses fbdev's default mmap code, which
has been written for I/O memory. Provide an mmap that uses GEM's mmap
infrastructure.

Utilize fine-grained fbdev macros to initialize struct fb_ops. The
macros set the read/write and the draw callbacks for DMA memory. Set
the fb_mmap callback to omapdrm's new mmap helper. Also select the
correct Kconfig token for fbdev's DMA helpers. Note that the DMA
helpers are the same as for system memory.
