[PATCH net-next 8/9] net: dsa: mt7530: move autoneg handling to PCS validation

["Russell King (Oracle)" <rmk+kernel@armlinux.org.uk>]

Move the autoneg bit handling to the PCS validation, which allows us to
get rid of mt753x_phylink_validate() and rely on the default
phylink_generic_validate() implementation for the MAC side.
