Subject: [PATCH net-next 1/3] net: dpaa2-mac: use Autoneg bit rather than
 an_enabled

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. This means we use the same condition
as phylink_mii_c22_pcs_config().
