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

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 properties 'marvell,force-mdi-order-normal' and
'marvell,force-mdi-order-reverse' for that purpose.
