Subject[PATCH v4 1/4] drm/vc4: Reformat and export binner bo allocation helper
Date
Since we'll be using the binner bo allocation helper in other parts
of the driver, reformat it with a vc4_v3d prefix and pass the vc4 dev
directly to match other functions.

Make the function visible to the whole driver too.
