gbm: Export a plane getter function
This will be used by clients that need to know the number of planes
allocated for them on behalf of the GL or other API. The best current
example of this is when an extra "plane" is allocated to store
compression data for the primary plane.
v2: Return 1 for cases where there is no image, ie. dumb bo (Daniel)
