That's introducing one more order of clocks... Please keep it
consistent. The only existing case with ahb has it at after axi_m and
others. Why making things everytime differently?

I also to propose to finally drop the obvious comments, like "AHB
clock". It cannot be anything else. AXI Master / slave are descriptive,
so should stay.

Best regards,
Krzysztof
