usb: pd: Add timeout for mode change

Currently USB driver tries to set power role as none in mode
change and waits for disconnect followed by connect notifications
to set new mode. But there is a chance that it might fail if other
device is not dual-role capable.

When device connected to window host pc and try data role swap.
Device trying to change the mode and setting the power role none.
But host PC does not support this and device never switching back
to original role and device enumeration does not happening with
host pc connected.

Fix it by having timeouts in mode setting. Setting it to dual-role and
bail out in case of timeout happens.
