net: dsa: store CPU port pointer in the tree
A dsa_switch_tree instance holds a dsa_switch pointer and a port index
to identify the switch port to which the CPU is attached.
Now that the DSA layer has a dsa_port structure to hold this data, use
it to point the switch CPU port.
This patch simply substitutes s/dst->cpu_switch/dst->cpu_dp->ds/ and
s/dst->cpu_port/dst->cpu_dp->index/.
