drm/imagination: Use new generic compatible string
Follow-on from the companion dt-bindings change ("dt-bindings: gpu: img:
More explicit compatible strings"), deprecating "img,img-axe" in favour of
the more explicit combination of "img,img-rogue" and "img,img-axe-1-16m".
Since all relevant details are interrogated from the device at runtime,
we can match on the generic "img,img-rogue" and avoid adding more entries
with NULL data members (barring hardware quirks).
