[PATCH] usb: cdns3: continue probe even when USB PHY device does not exist

[Siddharth Vadapalli]

Prior to commit cd295286c786 ("usb: cdns3: avoid error messages if phys
don't exist"), cdns3_probe() errors out only on failing to initialize the
USB2/USB3 PHY. However, since commit cd295286c786, absence of the PHY
device is also treated as an error, resulting in a regression.

Extend commit cd295286c786 to treat -ENODEV as an acceptable return value
of generic_phy_get_by_name() and continue device probe as was the case
prior to the commit.

Fixes: cd295286c786 ("usb: cdns3: avoid error messages if phys don't exist")
