[ Upstream commit 3b857472f34faa7d11001afa5e158833812c98d7 ]
Playback of 44.1Khz contents with HDMI plugged returns "Invalid pipe config" because HDMI paths in the FW topology are configured to operate at 48Khz.
This patch filters out sampling rates not supported at hdac_hdmi_create_dais() to let user space SRC to do the converting.
