Vendors may use this to write custom messages to their bootloader, and
as the bootloader is under vendor control, this makes sense to allow.

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.

This is originally allowed in healthd but the permission
was not transfered to health HAL. A typical health HAL
implementation is likely to write battery info to kernel
logs.
