On current code, We check the iddig status to make sure that the id
status is indeed in low level, and then send HOST notification and
power on phy based on this state. But On some Rockchip platforms like
RK3328, the ID Detector pin is not cited, the default state of ID pin
is floating, so the iddig status is always 1 which means in device mode.
To resolve this problem, We need to further check whether usb2phy_reg
structure of utmi_iddig has been initialized or not. If not, We can't
use the iddig status as a judgment condition.
