ASoC: Intel: Skylake: Await purge request ack on CNL
commit 7693cadac86548b30389a6e11d78c38db654f393 upstream.
Each purge request is sent by driver after master core is powered up and
unresetted but before it is unstalled. On unstall, ROM begins processing
the request and initializing environment for FW load. Host should await
ROM's ack before moving forward. Without doing so, ROM init poll may
start too early and false timeouts can occur.
