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

From: Paul Serice <paul@serice.net>

The workaround in commit f7201c3dcd7799f2aa3d6ec427b194225360ecee
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.
