MSM SoC has chipidea USB controller. So use ci13xxx_udc core.
This driver depends on transceiver driver for clock control,
PHY initialization, VBUS detection.  Register for notify_event
callback to perform MSM specific quirks after controller is reset
and stopped.

Introduces ci13xxx_udc_driver struct for bus glue drivers to hint
ci13xxx_udc core about their special requirements.  The flags include
avoiding hardware register access when controller is not in peripheral
mode, enabling pull-up upon VBUS, disabling streaming mode and dependency
on transceiver driver.

Initialize gadget_ops in udc_probe so that transceiver can notify VBUS
presence even when no gadget driver is bounded.

A notify_event callback is embedded in the same struct. This patch implements
two events called CONTROLLER_RESET_EVENT and CONTROLLER_STOPPED_EVENT to
notify the bus glue driver after resetting and stopping the controller for
performing SoC specific quirks.

Commit 06c3859f (usb: gadget/imx-udc: remove usage of deprecated symbol
USBD_INT0) was a bit precipitant because the name used instead didn't
match the usual naming scheme for irqs on arm/imx.  I renamed the irq to
the right name in e0830004 (ARM: imx: dynamically allocate imx_udc
device) when 06c3859f didn't hit Linus' tree, so I missed to add a
compat #define.

This patch allows compiling imx_udc.c with and without e0830004.

This commit fixes some issues with File-backed Storage Gadget
error recovery when registering LUN's devices.

First of all, when device_register() fails the device still
needs to be put.  However, because lun_release() decreases
fsg->ref reference counter the counter must be incremented
beforehand.

Second of all, after any of the device_create_file()s fails,
device_unregister() is called which in turn (indirectly) calls
lun_release() which decrements fsg->ref.  So, again, the
reference counter must be incremented beforehand.

Lastly, if the first or the second device_create_file()
succeeds, the files are never removed.  To fix it,
device_remove_file() needs to be called.  This is done by
simply marking LUN as registered prior to creating files so
that fsg_unbind() can handle removing files.

Instead of always assigning an increasing inode number in new_inode
move the call to assign it into those callers that actually need it.
For now callers that need it is estimated conservatively, that is
the call is added to all filesystems that do not assign an i_ino
by themselves.  For a few more filesystems we can avoid assigning
any inode number given that they aren't user visible, and for others
it could be done lazily when an inode number is actually needed,

The goku_remove() function can be called before device_register() so it

As I was changing the error handling in goku_probe(), I noticed that
