In mt8195, there are some larbs connect with the smi-sub-common, then
connect with smi-common.
Not critical but I suggest to describe what is smi-sub-common.
e.g. "some larbs are not directly connected to smi-common,
they are connected to smi-sub-common which is a bridge(?) interface to..."
OK. I will add some brief description about this sub-common in next
version.

Before we create device link between smi-larb with smi-common. If we have
sub-common, we should use device link the smi-larb and smi-sub-common,
then use device link between the smi-sub-common with smi-common. This is
for enabling clock/power automatically.

Move the device link code to a new interface for reusing.

There is no SW extra setting for smi-sub-common.
