[PATCH v4 4/5] net: stmmac: dwmac-sun8i: choose internal PHY via phy-is-integrated

[Corentin Labbe <clabbe.montjoie@xxxxxxxxx>]

The current way to find if the phy is internal is to compare DT phy-mode
and emac_variant/internal_phy.
But it will negate a possible future SoC where an external PHY use the
same phy mode than the internal one.

This patch adds a new way to find if the PHY is internal, via
the phy-is-integrated property.

Since the internal_phy variable does not need anymore to contain the xMII mode
used by the internal PHY, it is still used for knowing the presence of an
internal PHY, so it is modified to a boolean soc_has_internal_phy.
