phy: rockchip-inno-usb2: reduce the otg schedule delay time

Browse Source 
Reduce the otg schedule delay time from 6s to 1s to do
the first time usb charger detection earlier when power
on system with usb cable connect to PC USB. Because the
usb connection willed be disconnectted during usb charger
detection.

And the patch also makes the phy detect the usb disconnetion
more quickly after usb cable plug out.
