ASoC: msm: 8974: Add HDMI codec driver

Currently HDMI audio support is implemented with HDMI CPU driver and
dummy codec driver. HDMI CPU DAI configures both QDSP6 AFE and also
HDMI controller. This patch moves the functionality of HDMI codec
driver out of combined HDMI CPU and codec driver into a ASoc codec
driver.
