New devices define a profile field in the button configuration. This
allows us to map a button to set the target profile as active. Even
though we don't support configuring this right now, some devices, such
as the G915/G815, come pre-configured with this action on th M-Keys.
This patch makes us able to read and write those settings, this way they
don't get lost when we write a profile to the device.
