ASRock E350M1: Let `BiosGnbPcieSlotReset()` return `AGESA_UNSUPPORTED`

Quoting Jens Rottmann [1]:

Nevertheless I still think this whole function is bogus for the E350M1.  The
    function assumes GPIO21 is wired to reset APU PCIe lane 0+1 (PCIe x8, port 4+5
    as Coreboot/AGESA calls it), GPIO25 resets lane 2 (PCIe x4) and GPIO02 lane 3.
    But the E350M1 has PCIe x16 i.e. probably APU lanes 0-3 bundled, completely
    different layout.  They could have chosen GPIO21 to force resets, or 25 - or
    maybe 50 like on the Persimmon or any other they fancied or - and this is the
    most probable - none at all.  Having BiosGnbPcieSlotReset() toggle some GPIOs
    without knowing what they do on the E350M1 (if anything at all) is nonsense.
    In my opinion this whole function should just "return AGESA_UNSUPPORTED" and
    good riddance.
