In case we found a matching USB PHY in usb_get_phy() but the call to
try_module_get() fails, we shouldn't return a (probably soon dangling)
pointer but an ERR_PTR instead.

the PHY layer is supposed to be optional,
considering some PHY have no control bus
for SW to poke around.
After commit 1ae5799 (usb: hcd: Initialize
USB phy if needed) any HCD which didn't provide
a PHY driver would emit annoying error messages.
In this patch we're decreasing those messages
to debugging only and we also add a PHY prefix
or use dev_dbg so we know where they're coming from.

We need to initialize the notifer before use it.
So lets initialize it when add a new phy device to
reduce the code redundancy.

The callers are expecting an ERR_PTR value in case
of an error. Change he code to return with an encoded
-ENOMEM value in the case of a failed devres_alloc call.

The symbol usb_bind_phy is exported and annotated __init.
It looks like section mismatch. Fix by removing the
__init annotation of usb_bind_phy.

we only want GPL users for our generic functions,
so let's switch over to EXPORT_SYMBOL_GPL.

Most of otg/otg.c is not otg specific, but phy specific, so move it
to the phy directory.
