Since commit "193ab2a6 usb: gadget: allow multiple gadgets to be built"
the udc controllers can be compiled as a module. The ci13xxx_msm driver
is missing the MODULE_LICENSE statement, so loading fails with:

ci13xxx_msm: module license 'unspecified' taints kernel.
ci13xxx_msm: Unknown symbol dev_set_name (err 0)
ci13xxx_msm: Unknown symbol platform_get_irq (err 0)
ci13xxx_msm: Unknown symbol device_unregister (err 0)
ci13xxx_msm: Unknown symbol usb_add_gadget_udc (err 0)
ci13xxx_msm: Unknown symbol put_device (err 0)
ci13xxx_msm: Unknown symbol platform_driver_register (err 0)
ci13xxx_msm: Unknown symbol platform_get_resource (err 0)
ci13xxx_msm: Unknown symbol device_register (err 0)
ci13xxx_msm: Unknown symbol usb_del_gadget_udc (err 0)

This patch adds the missing MODULE_LICENSE statement with GPL v2 according
to the header of the driver.

OTG driver takes care of putting hardware in low power mode.  Hence
not registered for any runtime PM callbacks.

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.
