net: stmmac: check fwnode for phy device before scanning for phy
Some DT devices already have phy device configured in the DT/ACPI.
Current implementation scans for a phy unconditionally even though
there is a phy listed in the DT/ACPI and already attached.
We should check the fwnode if there is any phy device listed in
fwnode and decide whether to scan for a phy to attach to.
Fixes: fe2cfbc96803 ("net: stmmac: check if MAC needs to attach to a PHY")
