Removing status="disabled" from tegra20.dtsi makes this patch obsolete.

Although that said, since many of the USB properties are board-specific
and determined by system characterization, they aren't generally
applicable to all Tegra devices. As such, should those values be moved
into tegra-seaboard.dts instead? Perhaps tegra20.dtsi should specify
the default values that the driver currently uses if not supplied with
platform data though... I think the Seaboard values are the defaults,
which still would make this patch obsolete.
