net: stmmac: overwrite the dma_cap.addr64 according to HW design
The current IP register MAC_HW_Feature1[ADDR64] only defines
32/40/64 bit width, but some SOCs support others like i.MX8MP
support 34 bits but it maps to 40 bits width in MAC_HW_Feature1[ADDR64].
So overwrite dma_cap.addr64 according to HW real design.
