dump is read-only, this patch allows changing the registers. Some
actions, e.g., HP filter reset, is also done by *reading* a register,
so dumping all registers could affect behavior in uninteneded ways.

(And personally I think it's easier to use)


Anyway, I won't push for this to be applied, but I know I've had use
for it locally. I'm looking a bit at setting a threshold for the
interrupts, and this makes it easier to test without writing the code.
