Subject: [PATCHv3 (net.git) 0/2] stmmac: MDIO fixes

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	|
 	-------------------------------
