ASoC: qcom: sc8280xp: Limit speaker digital volumes
commit 716d4e5373e9d1ae993485ab2e3b893bf7104fb1 upstream.
Limit the speaker digital gains to 0dB so that the users will not damage them.
Currently there is a limit in UCM, but this does not stop the user form
changing the digital gains from command line. So limit this in driver
which makes the speakers more safer without active speaker protection in
place.
