[PATCH] net: stmmac: dwmac-qcom-ethqos: Enable support for XGMAC

All Qualcomm platforms have only supported EMAC version 4 until
now whereas in future we will also be supporting XGMAC version
which has higher capabilities than its peer. As both has_gmac4
and has_xgmac fields cannot co-exist, make sure to disable the
former flag when has_xgmac  is enabled.

We want to keep the default capabilities as EMAC4 and enable
XGMAC support from the dtsi based on the platform needs.
