Regression in ARM CLCD Fb

Commit 25348160e9a4 ("video: ARM CLCD: add special panel hook for
Versatiles") broke CLCD framebuffer on my qemu-system-arm +
vexpress-v2p-ca9.dtb + Android test setup.

Android boot failed with:

E/SurfaceFlinger( 1003): ERROR: failed to open framebuffer (No such
file or directory), aborting

It means Android didn't find /dev/fb* or equivalent /dev/graphics/fb*.

Any thoughts on what might be going wrong here? Or am I missing
anything obvious in my Qemu setup, though it was working fine so far.
I'd be happy to help debug things.
