Subject: [PATCH] sdm660-common: DeviceSettings: Access dirac from
 device-settings - Split preferences from audio category to avoid removing
 whole category upon nonexsting single preference - Previously there were only
 headphone and microphone gain which were from same kernel driver and it was
 logical   to remove the category when one of the preferences does not exist.
