All four Qualcomm SoC macro codecs define DAI IDs in an enum starting
with AIF_INVALID=0, which is nowhere used in the code thus actual DAI
IDs start from 1.  Drivers do not have their own of_xlate_dai_name(),
thus snd_soc_get_dlc() expects the DTS to start numbering DAIs from 0,
which creates confusing debugging scenario, e.g. DTS should use
<&lpass_wsamacro 2> for WSA_MACRO_AIF_VI with dai->id=3.

This also wastes some space, because drivers allocate few arrays for all
DAIs and basically the [0] is never used.

Drop the confusing first AIF_INVALID DAI identifier so the enum with DAI
IDs will start from 0.  This has little functional impact and does not
affect the ABI, except saving a few bytes of memory per driver.
