====================
net: dsa: microchip: common spi probe for the ksz series switches - part 2

This patch series aims to refactor the ksz_switch_register routine to have the
common flow for the ksz series switch. And this is the follow up patch series.

First, it tries moves the common implementation in the setup from individual
files to ksz_setup. Then implements the common dsa_switch_ops structure instead
of independent registration. And then moves the ksz_dev_ops to ksz_common.c,
it allows the dynamic detection of which ksz_dev_ops to be used based on
the switch detection function.

Finally, the patch updates the ksz_spi probe function to be same for all the
ksz_switches.
