ASoC: Intel: Skylake: Disable clock gating during firmware and library download
[ Upstream commit d5cc0a1fcbb5ddbef9fdd4c4a978da3254ddbf37 ]
During firmware and library download, sometimes it is observed that
firmware and library download is timed-out resulting into probe failure.
This patch disables dynamic clock gating while firmware and library
download.
