Fix for data and roaming icons

- Enable data connected flag based on the data state.

- Do not display data icon in data connected state
if radio type is unknown

- Display data icon independent of voice service state
i.e even if voice network is unavailable

- Show cdma roaming indicators if either voice
or data is roaming.

- Cleanup roaming indicator default values.
Set default CDMA Eri index to roaming off

- Show service if either voice/data is in
service if ro.config.combined_signal is true

- Consider eri only when in service

- Add in service check to isCdmaEri.
roaming related information
in registration state will not be valid
during out of service.
