Don't get it. What exactly are you trying to dump?
This patch dumps CTRL0, CTRL1, CTRL2, DEVSEL but also some registers
of APBH channel0 which is reserved....
Then it prints some debug info on channel 1 (ssp1) and then alle
channel 2 register except the debug register (ssp2 = not used here).

What info do you need?
