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.
