net: dsa: microchip: use ksz_chip_reg for

This patch series tries to use the same approach as struct ksz8 for
register which has different address for different switch family. It
moves the struct ksz8 from ksz8.h to struct ksz_chip_reg. Based on the
switch detect, the corresponding mask, reg and shifts are assigned.
