ASoC: Intel: hdac_hdmi: Limit sampling rates at dai creation
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.
