phy: amlogic: phy-meson-gxl-usb2: keep ID pull-up even in Host mode
In order to keep OTG ID detection even when in Host mode, the ID line of the PHY (if the current phy is an OTG one) pull-up should be kept enable in both modes. This fixes OTG switch on GXL, GXM & AXG platforms, otherwise once switched to Host, the ID detection doesn't work anymore to switch back to Device.
