Linus Walleij 43915b2f4b dt-bindings: marvell: Rewrite MV88E6xxx in schema
This is an attempt to rewrite the Marvell MV88E6xxx switch bindings
in YAML schema.

The current text binding says:
  WARNING: This binding is currently unstable. Do not program it into a
  FLASH never to be changed again. Once this binding is stable, this
  warning will be removed.

Well that never happened before we switched to YAML markup,
we can't have it like this, what about fixing the mess?

description:
The Marvell MV88E6xxx switch series has been produced and sold
by Marvell since at least 2008. The switch has a few compatibles which
just indicate the base address of the switch, then operating systems
can investigate switch ID registers to find out which actual version
of the switch it is dealing with.

description: |
marvell,mv88e6085: This switch uses base address 0x10.
This switch and its siblings will be autodetected from
ID registers found in the switch, so only "marvell,mv88e6085" should be
specified. This includes the following list of MV88Exxxx switches:
6085, 6095, 6097, 6123, 6131, 6141, 6161, 6165, 6171, 6172, 6175, 6176,
6185, 6240, 6320, 6321, 6341, 6350, 6351, 6352
marvell,mv88e6190: This switch uses base address 0x00.
This switch and its siblings will be autodetected from
ID registers found in the switch, so only "marvell,mv88e6190" should be
specified. This includes the following list of MV88Exxxx switches:
6190, 6190X, 6191, 6290, 6361, 6390, 6390X
marvell,mv88e6250: This switch uses base address 0x08 or 0x18.
This switch and its siblings will be autodetected from
ID registers found in the switch, so only "marvell,mv88e6250" should be
