Values of the following properties are set by SoC vendors on some
devices including Pixels.
- persist.bluetooth.a2dp_offload.cap
- persist.bluetooth.a2dp_offload.enable
- persist.vendor.bluetooth.a2dp_offload.enable
- ro.bt.bdaddr_path
- wlan.driver.status
So they should be whitelisted for compatibility.
Bug: 77633703
Test: succeeded building and tested with Pixels
