This patch converts the drivers in drivers/usb/gadget/* to use
module_pci_driver() macro which makes the code smaller and a bit simpler.

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.

Move PCI bus code from ci13xxx_udc to a new file ci13xxx_pci. SoC's
which has MIPS USB core can include the ci13xxx_udc and keep bus glue
code in their respective gadget controller drivers.
