To make the code more comparable to KSZ9477 code, move DSA
configurations to the same location.

Since you moved dsa related items to ksz8_setup, remaining items in
ksz8_switch_init are
- dev->cpu_port - Used in ksz_setup but called after the individual
switch setup function. We can move it ksz8_setup.
- dev->phy_port_cnt - Used in ksz8_vlan_filtering and
ksz8_config_cpuport. We can move.
- dev->port_mask - used in ksz_switch_register. So we cannot move.

To make the ksz8_switch_init and ksz9477_switch_init function similar,
we can move dev->cpu_port and dev->phy_port_cnt from ksz8_switch_init
to ksz8_setup
