1. Tools: Topology2: Add IIR, FIR, DRC to HDA analog playback …

   This patch replaces pipeline mixout-gain-dai-copier-playback with
   mixout-gain-efx-dai-copier-playback. The purpose is to allow
   enhance of audio playback quality with equalizers (IIR and FIR)
   and dynamic range control (DRC).
   
   The components are programmed by default to passthrough for minimal
   overhead. They can be activated via sof-ctl or UCM with ALSA controls.
   
   - Post Mixer Analog Playback IIR Eq bytes
   - Post Mixer Analog Playback FIR Eq bytes
   - Post Mixer Analog Playback DRC bytes
   - Post Mixer Analog Playback DRC switch
   
   The recommendation is to keep headphone playback flat and enable
   processing only when HDA output is in speaker mode.
