realtek: pcs: carve out media selection as generic

Browse Source 
So far, RTL931x implemented its media selection logic within
setup_serdes, unavailable to potential other users. One of those is
RTL930x which needs this too. To easy further refactoring, carve out the
logic to a generic helper providing the equal selection for all variants
anyway.
