Wayne Chang 9cb3ace502 phy: tegra: xusb: Add API to retrieve the port number of phy
[ Upstream commit d843f031d9 ]

This patch introduces a new API, tegra_xusb_padctl_get_port_number,
to the Tegra XUSB Pad Controller driver. This API is used to identify
the USB port that is associated with a given PHY.

The function takes a PHY pointer for either a USB2 PHY or USB3 PHY as input
and returns the corresponding port number. If the PHY pointer is invalid,
it returns -ENODEV.
