m2k: standalone: Disable DMA debug registers 

The debug register logic for the DMA take up a fair amount of resources.
Disabling them frees up space in the FPGA and also helps a bit with power.
Since those registers are mainly useful in development and not so much in
production the change shouldn't have any visible external effects.

It is possible to re-enable the debug registers by setting DEBUG_BUILD=1.
