These two patches are to fix the recent regressions raised
when test the stmmac on some platforms due to broken MDIO/PHY
management.
V2: use is_pseudo_fixed_link
V3: enforce the driver to support other configurations
The mdio bus will be allocated in case of a phy transceiver is on board;
it will be NULL if the fixed-link is configured.
If there is the "snps,dwmac-mdio" sub-node the mdio will be allocated
in any case (for DSA, mdio must be registered even if fixed-link).
The table below sums the supported configurations:
-------------------------------
snps,phy-addr | Y
-------------------------------
phy-handle | Y
-------------------------------
fixed-link | N
-------------------------------
snps,dwmac-mdio |
even if | Y
fixed-link |
-------------------------------
