net: stmmac: Introduce stmmac_fpe_supported()

Browse source

A single "priv->dma_cap.fpesel" checks HW capability only,
while both HW capability and driver capability shall be
checked by later refactoring to prevent unexpected behavior
for FPE on unsupported MAC cores and keep FPE as an optional
implementation for current and new MAC cores.
