arm/dts: hammerhead: Remove erroneous qcom,msm-bus,active-only property

qcom,msm-bus,active-only is a boolean and not an integer. As a
result, setting "active-only = <0>" was actually enabling it.

Reference: kernel_msm, commit ba514f1fc.

sound: wcd9320: tidy up things a little bit. Only accept signed values from now on. The 'headset gain' will only be used to remove some gain noise, increasing it beyond 1 step above the default doesn't make a difference so rather just have it decrease the gain.
