[PATCH RESEND 6/8] fbdev: vesafb: bind to platform-framebuffer device

[David Herrmann <dh.herrmann@gmail.com>]

x86 creates platform-framebuffer platform devices for every system
framebuffer. Use these instead of creating a dummy device.

This requires us to remove the __init annotations as hotplugging may occur
during runtime.
