usb: xhci: plat: remove error log for failure to get usb-phy

Remove this log to avoid non-error conditions.
If CONFIG_USB_PHY is disabled, the following error message appears:
[    0.231609] xhci-hcd f10f0000.usb3: xhci_plat_probe get usb3phy fail (ret=-6)
[    0.239716] xhci-hcd f10f8000.usb3: xhci_plat_probe get usb3phy fail (ret=-6)
In this case, devm_usb_get_phy_by_phandle is declared static inline
and returns -ENXIO.

It is easy to pinpoint the failure to get the usb-phy using the debug
log in drivers/usb/phy/phy.c. Therefore, it can be removed.
