Subject: [PATCH v1 1/1] soundwire: qcom: disable stop clock on 1.3.0 and below

This patch returns back the behavior of disabling stop clock on soundwire
1.3.0 and below which seems to have been altered by accident which
results in broken audio on sdm845 + wcd9340. For example, on AYN Odin and
Lenovo Yoga C630 devices.
