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.

The Amlogic AXG is close to the GXL Glue but with a single OTG PHY.
It needs the same init sequence as GXL & GXM, but it seems it doesn't need
the host disconnect bit.

I've been waiting for Kishon's review of drivers/phy parts. I can take
the rest, but without Kishon's ack, drivers/phy will be left out.
