Public bug reported:

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 ).
