Subject: ASoC: Intel: Skylake: Disable clock gating during firmware and library download

From: Pardha Saradhi K <[email protected]>

[ 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.
