Usually for devicetree property names 'clock' is not abbreviated. So
'realtek,dmic-clock-rate' might be a better choice. Also mention in the
description that it is in Hz.

What is the unit of the delay time. Usually for properties for duration
there is also a suffix indicating the unit. E.g. realtk,dmic-delay-ms.
