axi_dmac: Set axi4lite address space size to 4k 

The AXI specification that the minimum address space size is 4k, make sure
the axi_dmac adheres to this.

Internally the register space is still 2k. This means the upper and lower
2k of the axi4lite register space will map to the same internal registers.
Software must not rely on this and only access the lower 2k to enable
compatibility in case the internal space grows in the future.
