usb: gadget: udc: renesas_usb3: should fail if devm_phy_get() returns error

Browse source

This patch fixes an issue that this driver ignores errors other than
the non-existence of the device, f.e. a memory allocation failure
in devm_phy_get(). So, this patch replaces devm_phy_get() with
devm_phy_optional_get().
