Fix device support for CM9 SamsungRIL.

Changes include:

- Removing hardcoded properties that are now provided by SamsungRIL and
  pppd_cdma.
- Use "ril.cdma.data_state" property instead of "ril.cdma.data_ready" to
  signal (re)start/stop of pppd_cdma service.
- No hardcode DNS addresses in pppd_runner, since they're now forwarded to
  SamsungRIL.
- /system/etc/ip-up script to pass network parameters to SamsungRIL.
