drm: sun4i: de2/de3: add generic blender register reference function
The DE2 and DE3 engines have a blender register range within the
mixer engine register map, whereas the DE33 separates this out into
a separate display group.
Prepare for this by adding a function to look the blender reference up,
with a subsequent patch to add a conditional based on the DE type.
