[PATCH v3] phy: amlogic: phy-meson-gxl-usb2: keep ID pull-up even in Host mode

[Neil Armstrong]

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.
