[PATCH net-next v3 1/2] dt-bindings: net: marvell,aquantia: add property to override MDI_CFG

[Daniel Golle <daniel@makrotopia.org>]

Usually the MDI pair order reversal configuration is defined by
bootstrap pin MDI_CFG. Some designs, however, require overriding the MDI
pair order and force either normal or reverse order.

Add property 'marvell,mdi-cfg-order' to allow forcing either normal or
reverse order of the MDI pairs.

Signed-off-by: Daniel Golle <daniel@makrotopia.org>

v3: use integer enum instead of two properties as suggested
v2: enforce mutually exclusive relationship of the two new properties in
    dt-schema.
