[PATCH v2] dt-bindings: net: marvell,orion-mdio: Fix examples

[Michał Grzelak]

As stated in marvell-orion-mdio.txt deleted in commit 0781434af811f
("dt-bindings: net: orion-mdio: Convert to JSON schema") if
'interrupts' property is present, width of 'reg' should be 0x84.
Otherwise, width of 'reg' should be 0x4. Fix 'examples:' and add
constraints checking whether 'interrupts' property is present
and validate it against fixed values in reg.

Signed-off-by: Michał Grzelak <mig@xxxxxxxxxxxx>

Changelog:
v1->v2:
- remove second example
- add 'if:' constraint to 'allOf:'
- move 'allOf:' before 'examples:'
