net: dsa: b53: Set correct number of ports in the DSA struct
[ Upstream commit d12e1c4649883e8ca5e8ff341e1948b3b6313259 ]
Setting DSA_MAX_PORTS caused DSA to call b53 callbacks (e.g.
b53_disable_port() during dsa_register_switch()) for invalid
(non-existent) ports. That made b53 modify unrelated registers and is
one of reasons for a broken BCM5301x support.
This problem exists for years but DSA_MAX_PORTS usage has changed few
times. It seems the most accurate to reference commit dropping
dsa_switch_alloc() in the Fixes tag.
Fixes: 7e99e3470172 ("net: dsa: remove dsa_switch_alloc helper")
