Lars-Peter Clausen 4e0d68fde8 axi_dmac: Configure AXI address width according to the mapped address space
Currently the AXI address width of the DMA is always 32-bit. But not all
address spaces are so large that they require 32-bit to address all memory.

Extract the size of the address space that the DMA is connected too and
configure reduce the address size to the minimum required to address the
full address space.

This slightly reduces utilization.

If no mapped address space can be found the default of 32 bits is used for
the address.
