From: Nazim Amirul <[email protected]>
The Agilex5 SoCDK TSN Config2 gmac1 path includes an FPGA soft-IP
GMII-to-RGMII converter between the DWXGMAC and the PHY. The converter
provides the RGMII TX/RX delays and presents GMII toward the MAC, unlike
a plain altr,socfpga-stmmac-agilex5 port with no such converter.
Add altr,socfpga-stmmac-agilex5-tsn for that integration. It is not
listed as compatible with altr,socfpga-stmmac-agilex5 because the
converter presents GMII to the MAC and supplies the RGMII delays,
unlike a plain Agilex5 GMAC port.

v5: Drop altr,socfpga-stmmac-agilex5 fallback and rewrite commit message
to explain hardware incompatibility, per Krzysztof Kozlowski.
v4: No changes from v2.
