[PATCH net-next v6 02/12] net: usb: lan78xx: remove explicit check for missing PHY driver

[Oleksij Rempel]

RGMII timing correctness relies on the PHY providing internal delays.
This is typically ensured via PHY driver, strap pins, or PCB layout.

Explicitly checking for a PHY driver here is unnecessary and non-standard.
This logic applies to all MACs, not just LAN78xx, and should be left to
phylib, phylink, or platform configuration.

Drop the check and rely on standard subsystem behavior.
