mach-midas:increase usb charging to 1700
USB hubs that can't provide this output will default to the highest
possible output it can provide. We've set it at 1700 as using GPS, BT,
WiFi Tethering and Data while plugged into a USB port can't adequately
supply the power required to charge the device at the defaults of 475
and 450 respectively. 1700 is the value used by default for the AC and
Dock charging output so we're bringing USB charging up to the known
maximum safe charging value.
