The OTG state machine needs a mechanism to start and
stop the gadget controller as well as connect/disconnect
from the bus. Add usb_gadget_start(), usb_gadget_stop()
and usb_gadget_connect_control().

to register a gadget controller tha

The OTG controller and the USB controller can be linked via the
'otg-controller' property in the USB controller's device node.
of_usb_get_otg() can be used to get the OTG controller device
from the USB controller's device node.

Move the settings of PHY to a work queue and schedule it after
rtl_ops.init().
There are some reasons for this. First, the settings are only
needed for the first time initialization or after the power
down occurs.
Second, the settings are independent with the others.
Last, the settings may take
Move calling set_speed() from open() to rtl_hw_phy_work_func_t().
Then, we would set the default speed only for first initialization
or after resuming.
Besides, the set_speed() could handle the flag of PHY_RESET which
would be set in rtl_ops.hw_phy_cfg().
