conf: HdmiLpeAudio: add support for 3 devices

The LPE Audio mode on BYT/CHT supports up to 3 devices, and also supports
IEC61937 passthrough. Add missing alsa-lib configurations so that
apps can use the usual -D'hdmi:CARD=X,DEV=Y,AES0=0x[4|6]' syntax, e.g.

aplay -D'hdmi:CARD=0,DEV=2,AES0=0x6' -c2 -r48000 -fs16_le
ac3_surround_test.spdif

Tested on Zotac PI330 with Onkyo receiver
