i9082: set ro.telephony.call_ring=0

This allows UNSOL_CALL_RING to be faked by the upper layers at
appropriate times. Requires an additional patch.

Revert "i9082: fix non-looping ringtones ringing only once"

This causes UNSOL_CALL_RING to be sent twice (and the second
one sent at sometimes inappropriate time, leading to wrong
ringtone to be played for custom per-contact ringtone due to
a race condition in CallNotifier.)

This reverts commit aa4ba942b1bad5a49150d6818cfeff39837b67e7.
