ARM: tegra: TrimSlice: add support for USB1 port
TrimSlice's USB1 port has two purposes; it either acts as a device port
hosting Tegra's USB recovery protocol, or acts as a host port connected
to the internal USB->SATA bridge chip, which may in turn be connected to
an SSD or HDD. Add the appropriate device tree and board configuration
options to enable this port as a host port, and route the port to the
SATA bridge using the VBUS GPIO.
