[PATCH] ARM: tegra/harmony: enable USB host ports

[marc.zyngier@arm.com (Marc Zyngier)]

The Harmony board code doesn't have any support for USB, leaving
the board without any ethernet support. Add the necessary
declarations to have it up and running, at least for the J6 and J25
connectors, as well as the ethernet port.

The OTG port is left unused, short of any documentation.

Not sure if this is the right time to send this, as this should
eventually be handled by the device tree. May be useful to some
people in the meantime.

Patch against v3.0-rc2.
