Henry Tung 6d57b494c0 Create new system property type for Factory OTA could write system property
Due to Factory OTA client install in product partition but it also declare coredomian in
its sepolicy setting. That will let Factory OTA unable to find a property type could write system property.
But now Factory OTA have a restore NFC wake function need to write system property for communicate with bootloader.
So we need to create a new property type in system framework which could allow Factory OTA client to write system property.
