Dear Rob,
This nomencalture is extended to the MTK mt8183/mt8173.
And we think it's better to maintain multiple boards, but
the disadvantage is need to write one more machine drivers.

This property will assign to 'snd_soc_dai_link->platforms->of_node'.
The value of 'mediatek,platform' here is &afe that is mt8192 platform
driver.
It will be resolved from a phandle property to a device_node pointer.
