[PATCH 5.15 333/371] phy: tegra: xusb: Add missing tegra_xusb_port_unregister for usb2_port and ulpi_port

[Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>]

From: Gaosheng Cui <cuigaosheng1@xxxxxxxxxx>

[ Upstream commit e024854048e733391b31fe5a398704b31b9af803 ]

The tegra_xusb_port_unregister should be called when usb2_port
and ulpi_port map fails in tegra_xusb_add_usb2_port() or in
tegra_xusb_add_ulpi_port(), fix it.

Fixes: 53d2a715c240 ("phy: Add Tegra XUSB pad controller support")
