====================
Phylink integration improvements for Felix DSA driver

This is an overhaul of the Felix switch driver's phylink operations.

Patches 1, 3, 4 and 5 are cleanup, patch 2 is adding a new feature and
and patch 6 is adaptation to the new format of an existing phylink API
(mac_link_up).

Changes since v2:
- Replaced "PHYLINK" with "phylink".
- Rewrote commit message of patch 5/6.

Changes since v1:
- Now using phy_clear_bits and phy_set_bits instead of plain writes to
  MII_BMCR. This combines former patches 1/7 and 6/7 into a single new
  patch 1/6.
- Updated commit message of patch 5/6.
