[PATCH net-next 2/3] net: pcs: xpcs: use Autoneg bit rather than an_enabled

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

The Autoneg bit in the advertising bitmap and state->an_enabled are
always identical. Thus, we will be removing state->an_enabled.

Use the Autoneg bit in the advertising bitmap to indicate whether
autonegotiation should be used, rather than using the an_enabled
member which will be going away.
