usb: ulpi: Extend the existing ulpi framework.
Extend the existing ulpi viewport framework to pass the port number information for any ulpi ops. Fix the usage of ulpi api's accordingly. Tested-by: Stefano Babic <sbabic@denx.de> Acked-by: Igor Grinberg <grinberg@compulab.co.il> Signed-off-by: Govindraj.R <govindraj.raja@ti.com>
