[PATCH] USB: EHCI works again on NVidia controllers with >2GB RAM

From: Paul Serice <paul@serice.net>

The workaround in commit 4015d596da2821fcc1124c5033a1d956972ca0c7
broke.  The work around requires memory for DMA transfers for some
NVidia EHCI controllers to be below 2GB, but recent changes have
caused some DMA memory to be allocated before the DMA mask is set.
