Add an interface that allows drivers to claim a framebuffer and check
whether another driver has already claimed a framebuffer. Use this in
radeondrm(4) and simplefb(4) to prevent the latter from attaching if
radeondrm(4) is attached to the hardware that provides the framebuffer
set up by the firmware.
