Merge branch 'remove-phylink_state-s-an_enabled-member'

Russell King says:

====================
Remove phylink_state's an_enabled member

Now that all the fixes and correctness patches have been merged, it is
time to switch the two users that make use of .an_enabled to check the
Autoneg bit in the advertising mask, and finally remove the
.an_enabled member.

The first two patches remove the last uses of .an_enabled, which are
in DPAA2 and XPCS. The final patch removes the member.
