[PATCH net-next 03/10] net: dsa: microchip: make ksz_is_port_mac_global_usable() static

["Bastien Curutchet (Schneider Electric)" <bastien.curutchet@bootlin.com>]

ksz_is_port_mac_global_usable() is exposed in ksz_common.h while it's
only used internally.

Make ksz_is_port_mac_global_usable() static.
Move its definition above its first call.
