[U-Boot] [PATCH] usb: dwc3: Handle case where setup_phy is not needed

[Lukasz Majewski <lukma@denx.de>]

Hi Siva Durga Prasad Paladugu,

> returns ENOTSUPP which can be still valid and intentional
                                ^^^^^^^^^^^^^^^^^^^^^^^^^^^ - could you
                                elaborate on this a bit more?

What is the use case when -ENOTSUPP is valid and intentional ?

> so modify error check to handle this -ENOTSUPP.
