Previously, all Amlogic boards used the XTAL clock as the default board clock for the USB PHY input, so there was no need to enable it. However, with the introduction of new Amlogic SoCs like the A1 family, the USB PHY now uses a gated clock. Hence, it is necessary to enable this gated clock during the PHY initialization sequence, or disable it during the PHY exit, as appropriate.
