dt-bindings: net: marvell,aquantia: add property to override MDI_CFG

Browse Source 
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.
