[PATCH] fbdev: Pass struct device to class_simple_device_add

[PATCH] fbdev: Pass struct device to class_simple_device_add

Swsusp turns off the display when a power-management-enabled framebuffer
driver is used.  According to Nigel Cunningham <ncunningham@linuxmail.org>,
the fix may involve the following:

"...I thought the best approach would be to use device classes to find the
struct dev for the frame buffer driver, and then use the same code I use for
storage devices to avoid suspending the frame buffer until later..."

Changes:

- pass info->device to class_simple_device_add()
- add struct device *device to struct fb_info
- store struct device in framebuffer_alloc()
- for drivers not using framebuffer_alloc(), store the struct during
  initalization
- port i810fb and rivafb to use framebuffer_alloc()
