ro.telephony.call_ring.multiple is already in m7-common
keyguard.no_require_sim is already in full_base_telephony
telephony.sms.pseudo_multipart is handled in overlays
persist.eons.enabled is Sprint specific

 needed by Sprint CM

ro.ril.transmitpower
persist.radio.no_wait_for_card
ro.ril.wp.feature
persist.radio.add_power_save
