[PATCH net-next v2 1/2] dt-bindings: net: marvell,aquantia: add properties 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 mutually exclusive properties 'marvell,force-mdi-order-normal' and
'marvell,force-mdi-order-reverse' for that purpose.

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

v2: enforce mutually exclusive relationship of the two new properties in
    dt-schema.
