Adds the gadget data structure and appropriate data structure pointers
to the common dwc2_hsotg data structure. To keep the driver data
dereference code looking clean, the gadget variable declares are only available
for peripheral and dual-role mode. This is needed so that the dwc2_hsotg data
structure can be used by the hcd and gadget drivers.
Updates gadget.c to use the dwc2_hsotg data structure and gadget pointers
that have been moved into the common dwc2_hsotg structure.

Hcd controller needs bus_suspend/resume, dwc2 controller make
root hub generate suspend/resume signal with hprt0 register
when work in host mode.
After the root hub enter suspend, we can make controller enter
low power state with PCGCTL register.
We also update the lx_state for hsotg state.
This patch has tested on rk3288 with suspend/resume.

This patch expands USB-DMAC channels for R-Car Gen2 SoCs. The SoCs
have 4 channels. If d{2,3}_{t,x}x_id are not set, this driver never
uses the expanded USB-DMAC channels.

commit e47d925 (usb: move the OTG state from
the USB PHY to the OTG structure) moved the
OTG state from struct usb_phy to struct usb_otg.
Unfortunately, even though I fixed quite a few
build regressions with that patch already, this
one was still missing.
Note that this driver still has other randconfig
build problems which I'll leave for driver author
to fix, as that's less trivial.

SET_FEATURE request with DEBUG_MODE only worked the first time after module
initialisation. Per the USB 2.0 debug device specification, said request
is to be treated as if it were a SET_CONFIGURATION request, i.e. endpoint
must be re-configured.
As configure_endpoints() may now get called multiple times, move it outside
__init and move serial_alloc_tty() call into __init.
Code has assumption that endpoint mapping remains unchanged with consecutive
calls of configure_endpoints().

Converting hid to the new function interface requires converting
the USB hid's function code and its users.
This patch converts the f_hid.c to the new function interface.
The file can now be compiled into a separate usb_f_hid.ko module.
The old function interface is provided by means of a preprocessor
conditional directives. After all users are converted, the old interface
can be removed.

so just after that the usb composite is still available,
but there is no hid data any more.

Converting midi to the new function interface requires converting
the USB midi's function code and its users.
This patch converts the f_midi.c to the new function interface.
The file can now be compiled into a separate usb_f_midi.ko module.
The old function interface is provided by means of a preprocessor
conditional directives. After all users are converted, the old interface
can be removed.

The soundcard index to use for the ALSA device creation is passed as a
parameter to f_midi_bind_config(), but is assigned to midi->index only
after the call to f_midi_register_card(midi). So no matter what is passed
to f_midi_bind_config(), the actual index for snd_card_new() is always 0.
This probably works ok if at the moment of f_midi's bind there are no
other snd_cards, but if there are, it is not possible to bind f_midi.
This patch moves the assignment to a place before the call to
f_midi_register_card(midi).

Attaching a keyboard, using it as a wakeup via
|for f in $(find /sys/devices/ocp.3/47400000.usb -name wakeup)
|do
| echo enabled > $f
|done
going into standby
| echo standby > /sys/power/state
and now a wake up by a pressing a key.
What happens is that the system wakes up but the USB device is dead. The
USB stack tries to send a few control URBs but nothing comes back.
Eventually it gaves up and the device remains dead:
|[ 632.559678] PM: Wakeup source USB1_PHY
|[ 632.581074] PM: noirq resume of devices complete after 21.261 msecs

|[ 690.076601] PM: Finishing wakeup.

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.
