axi_dmac: Indicate that the core does not issue narrow AXI bursts 

The axi_dmac core does not issue narrow AXI bursts. Indicate this by
setting the SUPPORTS_NARROW_BURST property to 0 on both AXI master
interfaces.

This allows connected slaves to know that they will not receive narrow
bursts, which allows them to disable support for it.
