[PATCH 3/3] net-next: stmmac: dwmac-sun8i: choose internal PHY via compatible

[Corentin Labbe]

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 its
compatible.

Since the phy_mode of the internal PHY does need to be know, the
variant internal_phy member is converted to a boolean.
