Alex Deucher fa3d8456f7 fbdev: fbmem: add a helper to determine if an aperture is used by a fw fb
commit 9a45ac2320d0a6ae01880a30d4b86025fce4061b upstream.

Add a function for drivers to check if the a firmware initialized
fb is corresponds to their aperture.  This allows drivers to check if the
device corresponds to what the firmware set up as the display device.
