SystemUI: Porting serveral bug fix

1. The text size is too large to display completely on 8x10.
   Modify the text size in order to dislpay completely. Add a
   folder named values-w320dp to match the resolution.
2. Carrier name does NOT changed according to system locale
   settings. Make carrier name change with the system language
   by default, and update networkName immediately when locale
   is changed.
3. Change data roaming text in status bar.
4. Some carrier requires that BT/Wifi should not be turned
   on in airplane mode.
   We will not turn on BT/Wifi from quick setting if airplane
   mode is on.
5. Switch sub1 and sub3 icons.
6. Show battery icon for DSDS mode.
