Seppo Ingalsuo 23c7e4739c Topology: Add development example of demux and EQ band-split pipeline 
This patch adds topologies sof-apl-nocodec-demux-eq-2ch4ch.tplg and
sof-apl-nocodec-demux-eq-4ch4ch.tplg. Playback of 2ch creates 4ch
output in format L_lo, L_hi, R_lo, and R_hi. An example band-split
at 2 kHz is configured for EQ processing. The low band contains
an additional 80 Hz high-pass.

The pipeline was tested in UP2 device. The nocodec topology enables
an useful SPP loopback mode. The capture PCM is connected to DAI
loopback so this pipeline can be tested with simultaneous 2ch aplay
and 4ch arecord.
