Try to get the device's module clock if the dt has no clocks and
system-clock-frequency properties.

Li,

I am trying to have many DAI links in the simple-card, but I get an
error on getting the device clock: only the dma device needs a clock
and the spdif codec has none. What was the purpose of this default
device clock?
