[PATCH RFC net-next 3/9] net: phylink: pass aneg_mode into phylink_mii_c22_pcs_config()

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

Pass the aneg_mode into phylink_mii_c22_pcs_config() in preparation
to moving it up as a parameter passed to the pcs_config() method.
In doing so, we no longer need to pass the MLO_AN_* mode to this
function.
