Currently, 'res->flags' handlings are wrong in three respects:
* the driver _modifies_ the contents of platform data
* res->flags is set up, but not used anywhere in the driver
* request_irq() always takes VBUS_IRQ_FLAGS, regardless of refs->flags

This patch tries to fix this with a policy: If a platform IRQ resource
is available, give preference to its IRQ flag(s) over a default one
(VBUS_IRQ_FLAGS).

gpio_vbus is designed to be able to get an IRQ number for VBUS change
interrupt either (1) through platform_get_resource(IORESOURCE_IRQ) or
(2) by processing gpio_to_irq(pdata->gpio_vbus), in probe() function.

On the other hand, gpio_vbus_set_peripheral() and gpio_vbus_remove()
are always doing gpio_to_irq(pdata->gpio_vbus) to get an IRQ number.

This is not just inconsistent, but also broken.  There is no guarantee
that an IRQ number obtained by platform_get_resource() is equal to
gpio_to_irq(pdata->gpio_vbus).

Cache an IRQ number in probe() function, and use it where necessary.

Basically, ->vbus_session() calls should be served when VBUS session
starts and ends (it's not whenever transciever drivers detect VBUS
_changes_).  Otherwise, if UDC gadget drivers don't want for some
reason ->vbus_session() calls with the same "is_active" value, either
OTG or UDC drivers need to have some protection handlings.

Also, on platforms using this 'gpio_vbus' driver, the driver is only
allowed to check whether VBUS is applied.  There is no kernel-standard
way prepared for UDC gadget drivers to do that.

With this in mind, gpio_vbus should try to prevent unnecessary
consecutive vbus_session calls being served with the same "in_active"
value.

In commit c2344f13 (USB: gpio_vbus:
add delayed vbus_session calls, 2009-01-24), usb_gadget_vbus_connect()
and ...disconnect() were extracted from the interrupt handler, so to
allow vbus_session handlers to deal with msleep() calls.

This patch takes the approach one step further.

USB2.0 specification (7.1.7.3 Connect and Disconnect Signaling) says
that the USB system software (shall) provide a debounce interval with
a minimum duration of 100 ms, which ensures that the electrical and
mechanical connection is stable before software attempts to reset
the attached device.

Commit 9ad63986 (pda_power: Add support for using otg transceiver events)
converted the pda-power driver to use otg events to determine the status
of the power supply.

As gpio-vbus didn't use otg events until now, this change breaks setups
of pda-power with a gpio-vbus transceiver.

This patch adds the necessary otg events and notifiers to gpio-vbus.
