net: macb: Add DMA 64-bit address support for macb
Enable 32-bit or 64-bit DMA in the macb driver based on the macb
hardware compatibility and it is configured with structure macb_config
in the driver.
The Microchip PolarFire SoC Memory Protection Unit(MPU) gives the 64-bit
DMA access with the GEM, the MPU transactions on the AXI bus is 64-bit
not 32-bit So 64-bit DMA is enabled for the Microchip PolarFire SoC GEM.
