Bug Description

There are certain modem runtime errors that can leave the modem in an inconsistent state which requires a modem reset to fix. Our MTK modem implementation supports such a reset, but there isn't a generic rilmodem method for doing so.

See the following pull-request for a bug which describes a problem where failures deactivating a gprs-context ( aka APN ) can lead to the gprs atom getting stuck. The fix was to implement retry logic, however if the retry limit is hit, we reset MTK-based modems. This bug concerns adding a generic method to reset devices that use the rilmodem driver exclusively ( eg. mako ).
