 added OTG support to (default) script.bin

script.bin files on /dev/mmcblk0p1:
--------------------------------------------------
script.bin --> standard version with OTG enabled
script.bin.otg-off --> without OTG support
script.bin.otg-on --> same as standard file
--------------------------------------------------

Just copy script.bin.no-otg to script.bin to disable OTG

 OTG support causes load >= 1.00

 usb-hardware-sc goes in D state and load goes up to 1.00

root@bananapi /mnt # ps aux | awk '$8 ~ /D/ { print $0 }'
root 23 0.0 0.0 0 0 ? D 09:21 0:00 [usb-hardware-sc]
