fbdev: simplefb: mark as fw and allocate apertures
fbdev-core uses FBINFO_MISC_FIRMWARE to mark drivers that use firmware framebuffers. Furthermore, we now allocate apertures for the fbinfo device. Both information is used by remove_conflicting_framebuffers() to remove a fbdev device whenever a real driver is loaded. This is used heavily on x86 for VGA/vesa/EFI framebuffers, but is also of great use for all other systems. Especially with x86 support for simplefb, this information is needed to unload simplefb before a real hw-driver (like i915, radeon, nouveau) is loaded.
