net: dsa: microchip: bypass dev_ops->setup() and teardown() for lan937x

Browse source

The KSZ switch families are sufficiently different that a common
ds->ops->setup() - ksz_setup() with micro-managed dev_ops->reset(),
dev_ops->pcs_create(), dev_ops->config_cpu_port(),
dev_ops->enable_stp_addr(), dev_ops->setup() seems to be too convoluted.

I am proposing to make each KSZ switch family part ways for
dsa_switch_ops :: setup() and teardown(), to allow them greater
flexibility. This here is the implementation for lan937x, which is
nothing other than a copy of ksz_setup() with the dev_ops function
pointers replaced with direct function calls.
