net: dsa: microchip: remove VLAN operations for ksz8463

KSZ8463 uses the common KSZ8 implementation for its VLAN operations.
This implementation returns -ENOTSUPP for the KSZ8463 case, which is
pointless.

Remove the VLAN operations from the ksz8463_switch_ops so the core can
directly return -ENOTSUPP.
