MAX98390 is a smart amplifier and exposes one DAI, so '#sound-dai-cells'
property is needed for describing the DAI links.
Reference the dai-common.yaml schema to allow '#sound-dai-cells' to be
used.
This fixes dtbs_check error:
'#sound-dai-cells' does not match any of the regexes: 'pinctrl-[0-9]+'

Another wack-a-mole pass of killing off unnecessary 'allOf + $ref'
usage.
json-schema versions draft7 and earlier have a weird behavior in that
any keywords combined with a '$ref' are ignored (silently). The correct
form was to put a '$ref' under an 'allOf'. This behavior is now changed
in the 2019-09 json-schema spec and '$ref' can be mixed with other
keywords. The json-schema library doesn't yet support this, but the
tooling now does a fixup for this and either way works.
This has been a constant source of review comments, so let's change this
treewide so everyone copies the simpler syntax.
