Merge branch 'mv88e6393x'

Marek Behún says:

====================
Add support for mv88e6393x family of Marvell

after 2 months I finally had time to send v17 of Amethyst patches.

This series is tested on Marvell CN9130-CRB.

Changes since v16:
- dropped patches adding 5gbase-r, since they are already merged
- rebased onto net-next/master
- driver API renamed set_egress_flood() method into 2 methods for
  ucast/mcast floods, so this is fixed

Changes from v15:
- put 10000baseKR_Full back into phylink_validate method for Amethyst,
  it seems I misunderstood the meaning behind things and removed it
  from v15
- removed erratum 3.7, since the procedure is done anyway in
  mv88e6390_serdes_pcs_config
- renumbered errata 3.6 and 3.8 to 4.6 and 4.8, according to newer
  version of the errata document
- refactored errata code a little and removed duplicate macro
  definitions (for example MV88E6390_SGMII_CONTROL is already called
  MV88E6390_SGMII_BMCR)

Changes from v14:
- added my Signed-off-by tags to Pavana's patches, since I am sending
  them (as suggested by Andrew)
- added documentation to second patch adding 5gbase-r mode (as requested
  by Russell)
- added Reviewed-by tags
- applied Vladimir's suggestions:
  - reduced indentation level in mv88e6xxx_set_egress_port and
    mv88e6393x_serdes_port_config
  - removed 10000baseKR_Full from mv88e6393x_phylink_validate
  - removed PHY_INTERFACE_MODE_10GKR from mv88e6xxx_port_set_cmode

Changes from v13:
- added patch that wraps .set_egress_port into mv88e6xxx_set_egress_port,
  so that we do not have to set chip->*gress_dest_port members in every
  implementation of this method
- for the patch that adds Amethyst support:
  - added more information into commit message
  - added these methods for mv88e6393x_ops:
      .port_sync_link
      .port_setup_message_port
      .port_max_speed_mode (new implementation needed)
      .atu_get_hash
      .atu_set_hash
      .serdes_pcs_config
      .serdes_pcs_an_restart
      .serdes_pcs_link_up
  - this device can set upstream port per port, so implement
      .port_set_upstream_port
    instead of
      .set_cpu_port
  - removed USXGMII cmode (not yet supported, working on it)
  - added debug messages into mv88e6393x_port_set_speed_duplex
  - added Amethyst errata 4.5 (EEE should be disabled on SERDES ports)
  - fixed 5gbase-r serdes configuration and interrupt handling
  - refactored mv88e6393x_serdes_setup_errata
  - refactored mv88e6393x_port_policy_write
- added patch implementing .port_set_policy for Amethyst
