Subject: [RFC Patch net-next 16/17] net: dsa: microchip: common menuconfig for ksz series switch

This patch replaces the two different menuconfig for ksz9477 and ksz8795
to single ksz_common. so that it can be extended for the other switch
like lan937x. And removes the export_symbols for the extern functions in
the ksz_common.h.
