fbdev: defio and Metronomefb
Implement support for the E-Ink Metronome controller. It provides an mmapable
interface to the controller using defio support. It was tested with a gumstix
pxa255 with Vizplex media using Xfbdev and various X clients such as xeyes,
xpdf, xloadimage.
This patch also fixes the following bug: Defio would cause a hang on write
access to the framebuffer as the page fault would be called ad-infinitum. It
fixes fb_defio by setting the mapping to be used by page_mkclean.
