net: dsa: microchip: fix KSZ87xx family structure wrt the datasheet

Browse Source 
The KSZ87xx switches have 32 static MAC address table entries and not
8. This fixes -ENOSPC non-critical errors from ksz8_add_sta_mac when
configured as a bridge.

Add a new ksz87xx_dev_ops structure to be able to use the
ksz_r_mib_stat64 pointer for this family; this corrects a wrong
mib->counters cast to ksz88xx_stats_raw. This fixes iproute2
statistics. Rename ksz8_dev_ops structure to ksz88x3_dev_ops, in line
with ksz_is_* naming conventions from ksz_common.h.
