Testing with an Armada 8040 board shows that adding the generic-ahci
compatible to the CP110 AHCI nodes gets us working AHCI on the board.
A previous patch series posted by Thomas Petazzoni was retracted when
it was realised that the IP was supposed to be, and is, compatible
with the standard register layout.
Add this compatible.

Assuming the above is correct this looks sane to me. FWIW:

Applied on mvebu/dt64
(not that it didn't apply cleanly on the mainline because in mainline we
don't use yet the ICU for the interrupt)
