fbdev: fbcon: select VT_HW_CONSOLE_BINDING
fbdev provides framebuffer hotplugging, hence, we need to allow fbcon to unbind from framebuffers. Unfortunately, fbcon_fb_unbind() cannot unbind from the last framebuffer, unless console-unbinding is supported. Fixing fbcon_unbind() to return 0 caused some horrible NULL-derefs in the VT layer and I couldn't figure out why. Hence, lets just require console-unbinding so fbdev hotplugging works with fbcon.
