usb: manual delay 8s to enable connect pc

Android generate Serial number too later than set 1 to
sys/class/android_usb/android0/enable. So here we have to manual
delay some time to enable usb connect in usb controler driver,
otherwise adb read a wrong serial number via usb then CTS test
will fail.
