Subject: [PATCH net-next v3 00/10] net: dsa: mv88e6xxx: support for mv88e6250

This adds support for the mv88e6250 chip. Initially based on the
mv88e6240, this time around, I've been through each ->ops callback and
checked that it makes sense, either replacing with a 6250 specific
variant or dropping it if no equivalent functionality seems to exist
for the 6250. Along the way, I found a few oddities in the existing
code, mostly sent as separate patches/questions.

The one relevant to the 6250 is the ieee_pri_map callback, where the
existing mv88e6085_g1_ieee_pri_map() is actually wrong for many of the
existing users. I've put the mv88e6250_g1_ieee_pri_map() patch first
in case some of the existing chips get switched over to use that and
it is deemed important enough for -stable.

v3:
- rebase on top of net-next/master
- add reviewed-bys to patches unchanged from v2 (2,3,4,5)
- add 6250-specific ->ieee_pri_map, ->port_set_speed, ->port_link_state (1,6,7)
- in addition, use mv88e6065_phylink_validate for ->phylink_validate,
  and don't implement ->port_get_cmode, ->port_set_jumbo_size,
  ->port_disable_learn_limit, ->rmu_disable
- drop ptp support
- add patch adding the compatible string to the DT binding (9)
- add small refactoring patch (10)

v2:
- rebase on top of net-next/master
- add reviewed-by to two patches unchanged from v1 (2,3)
- add separate watchdog_ops
