Subject: [PATCH] dsa: correctly determine the number of switches in a system

The number of connected switches was sourced from the number of
children to the DSA node, change it to the number of available
children, skipping any disabled switches.

Fixes: 5e95329b701c4 ("dsa: add device tree bindings to register DSA switches")
