Since internal phy-mode is reserved for non-xMII protocol we cannot use
it with dwmac-sun8i.
Furthermore, all DT patchs which comes with this patch were cleaned, so
the current state is broken.
This reverts commit 1c2fa5f84683 ("net: stmmac: support future possible
different internal phy mode")
Fixes: 1c2fa5f84683 ("net: stmmac: support future possible different internal
phy mode")
