[PATCH v1 net-next 2/6] net: dsa: ocelot: felix: Remove requirement for PCS in felix devices

[Colin Foster]

Existing felix devices all have an initialized pcs array. Future devices
might not, so running a NULL check on the array before dereferencing it
will allow those future drivers to not crash at this point
