Well, there's one difference: on Armada XP we don't need to support the
"old" Device Tree, which didn't had the fixed 25 Mhz clock input
described.

So either we decide that it was a mistake due to an early version of
the 375 and we skip backward DT compatibility. Or we need in some way a
different logic than Armada XP, because Armada XP doesn't have this
backward compatibility requirement.
