net: stmmac: clear half-duplex caps where unsupported

Where a core supports hardware features, but does not indicate support
for half-duplex, clear phylink's half-duplex 1G, 100M and 10M
capability bits to disallow half-duplex operation and advertisement of
these link modes.

This will avoid the need for special code in the PCS driver to do this
based on the ESTATUS register bits, as the support in the PCS is
dependent on the same synthesis choice as the MAC core.
