fbcon: Call con2fb_map functions directly
These are actually fbcon ioctls which just happen to be exposed through /dev/fb*. They completely ignore which fb_info they're called on, and I think the userspace tool even hardcodes to /dev/fb0. Hence just forward the entire thing to fbcon.c wholesale. Note that this patch drops the fb_lock/unlock on the set side. Since the ioctl can operate on any fb (as passed in through con2fb.framebuffer) this is bogus. Also note that fbcon.c in general never calls fb_lock on anything, so this has been badly broken already. With this the last user of the fbcon notifier callback is gone, and we can garbage collect that too. v2: add missing uaccess.h include (alpha fails to compile otherwise), reported by kbuild. v3: Remember to also drop the #defines (Maarten) v4: Add the static inline to dummy functions.
