musb->int_usb already contains the correct
information for musb-core to handle babble.
In fact, this very check was just causing a
nonsensical babble interrupt storm.
With this I can get test.sh to run and, even though
all tests fail with timeout, that's still better
than locking up the system due to IRQ storm.
Also, if I remove g_zero and load g_mass_storage,
then everything works fine again.

We need a pm_runtime_get_sync() call from
within musb_gadget_pullup() to make sure
registers are accessible at that time.
The problem is that musb_gadget_pullup() is
called with IRQs disabled and, because of that,
we need to tell pm_runtime that this pm_runtime_get_sync()
is IRQ safe.
We can simply add pm_runtime_irq_safe(), however, because
we need to make our read/write accessor function pointers
have been initialized before trying to use them. This means
that all pm_runtime initialization for musb_core needs to
be moved down so that when we call pm_runtime_irq_safe(),
the pm_runtime_get_sync() that it calls on the parent, won't
cause a crash due to NULL musb_read/write accessors.

The reason for this backtrace is the attempt of the USB code to resume
the HUB twice and thus enqueue the status URB twice.
Alan Stern was a great help by explaining how the USB code supposed to
work and what is most likely the problem. The root problem is that after
resume the musb runtime-suspend state remains RPM_SUSPENDED.
According to git log it RPM was added for the omap2430 platform. If I
understand it correct the omap2430 invokes a get on musb once a cable is
connected and a put once the cable is gone. In between the device could
go auto-idle/off. Not sure what happens when the device goes into suspend
but then I guess it was gadget only.
On DSPS I see only a get in probe and put in remove function. This would
forbid RPM from working but then the devices enterns suspended state
anyway :)
To get rid of this warning, I set the device state to RPM_ACTIVE which
the expected state.

It seems that since we got woken up via MUSB_INTR_RESUME the
musb_host_finish_resume() callback is executed before the
resume-callbacks of the PHY and glue layer are invoked. If I delay it
until the glue layer resumed then I don't see this problem.
I also move musb_host_resume_root_hub() into that callback since I don't
see any reason in doing anything resume-link if there are still pieces
not restored.

The am335x-evmsk support two kinds of suspend:
- standby
the USB device remains powered while the system goes into suspend
- mem
the USB device becomes powerless while the system goes into suspend.
In the "standby" case the device resumes quickly. In the "mem" case the
system hangs for a few seconds. It seems to me that the USB-device has
no address (it was disconnected) and the USB stack thinks that it is
fully operational and GetPortStatus returns the status from before the
suspend so it is not a big help here.
This adds a check in the resume path to see if the device mode (A or B)
and the speed is the same. If the device went missing between
suspend/resume (VBUS went down) then MUSB seems to go into B mode and
HS/FS bits are cleared. In that case we clear the port1_status bits and
assume a disconnect. Once the stack learns this it does a "logical
disconnect" and removes the USB-device quickly. Should the device remain
connected during the suspend then MUSB will receives a "CONNECT" interrupt.
