dsa: lan9303: Move to PHYLINK

This patch series moves the lan9303 driver to use the phylink
api away from phylib.

Migrating to phylink means removing the .adjust_link api. The
functionality from the adjust_link is moved to the phylink_mac_link_up
api.  The code being removed only affected the cpu port.  The other
ports on the LAN9303 do not need anything from the phylink_mac_link_up
api.

Patches:
 0001 - Whitespace only change aligning the dsa_switch_ops members.
	No code changes.
 0002 - Moves the Turbo bit initialization out of the adjust_link api and
	places it in a driver initialization execution path. It only needs
	to be initialized once, it is never changed, and it is not a
	per-port flag.
 0003 - Adds exception handling logic in the extremely unlikely event that
	the read of the device fails.
 0004 - Performance optimization that skips a slow register write if there
	is no need to perform it.
 0005 - Change the way we identify the xMII port as phydev will be NULL
	when this logic is moved into phylink_mac_link_up.
 0006 - Removes adjust_link and begins using the phylink dsa_switch_ops
	apis.
 0007 - Adds XMII port flow control settings in the phylink_mac_link_up()
	api while cleaning up the ANEG / speed / duplex implementation.
---
v6->v7:
  - Moved the initialization of the Turbo bit into lan9303_setup().
  - Added a macro for determining is a port is an XMII port.
  - Added setting the XMII flow control in the phylink_mac_link_up() API.
  - removed unnecessary error handling and cleaned up the code flow in
    phylink_mac_link_up().
v5->v6:
  - Moved to using port number to identify xMII port for the LAN9303.
v4->v5:
  - Created prep patches to better show how things migrate.
  - cleaned up comments.
v3->v4:
  - Addressed whitespace issues as a separate patch.
  - Removed port_max_mtu api patch as it is unrelated to phylink migration.
  - Reworked the implementation to preserve the adjust_link functionality
    by including it in the phylink_mac_link_up api.
v2->v3:
  Added back in disabling Turbo Mode on the CPU MII interface.
  Removed the unnecessary clearing of the phy supported interfaces.
v1->v2:
  corrected the reported mtu size, removing ETH_HLEN and ETH_FCS_LEN
