tegra: usb: Fix device enumeration problem of USB1
tegra: usb: Fix device enumeration problem of USB1
A known hardware issue of USB1 port where bit 1 (connect status
change) of PORTSC register will be set after issuing Port Reset
(like "usb reset" in u-boot command line).
This will be treated as an error and stops later device enumeration.
Therefore we clear that bit after Port Reset in order to proceed
later device enumeration.
