Artem Leonenko 0a313c4d24 USB: gadget: ci13xxx: don't assume that PAGE_SIZE is 4096
Page size for transaction descriptors for CI13XXX has nothing
common with page size from MM. Using platform and configuration
specific PAGE_SIZE is wrong.

Pavankumar Kondeti f01ef5748f USB: gadget: Introduce ci13xxx_udc_driver struct
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.
