Prashanth K f776b94ccd usb: common: usb-conn-gpio: Prevent bailing out if initial role is none
commit 8e21a620c7 upstream.

Currently if we bootup a device without cable connected, then
usb-conn-gpio won't call set_role() because last_role is same
as current role. This happens since last_role gets initialised
to zero during the probe.

To avoid this, add a new flag initial_detection into struct
usb_conn_info, which prevents bailing out during initial
detection.
