[PATCH] ASoC: dt-bindings: maxim,max98357a: Add compatible with richtek,rt9123

[cy_huang]

From: ChiYuan Huang <cy_huang@xxxxxxxxxxx>

The hardware control and specification of 'richtek,rt9123' are similar
with max98357 or max98360. It's no need to add the new source code. So
make it compatible with one of them.
