viafb: Separate global and fb-specific data 

This patch moves data of interest into a new viafb_dev structure which
describes the device as a whole; the idea here is to create a separation
between what all devices may need and what the framebuffer device in
particular needs.

I've also made some small steps toward thinning out the global.h mess.
