at91: Backport determine_rate prototype fix

Browse Source 
This patch is backport of a fix to a USB prototype mismatch bug found
in 3.18 kernels, originally submitted by Boris Brezillon [1].
The symptom of this bug was that devices attached to the at91 using
at91_ohci on a hub never appeared and failed to initialise.
