DSP: Convert accelerator to a C++ class 

Slightly cleaner, allows DSP accelerator behaviour to be
added to both HLE and LLE pretty easily, and makes the accelerator
easier to unit test.

I chose to include all accelerator state as private members, and
to expose state that is accessible via registers with getters/setters.
It's more verbose, yes, but it makes it very clear what is part of
the accelerator state and what isn't (e.g. coefs).

This works quite well for registers, since the accelerator can do
whatever it wants internally. For example, the start/end/current
addresses are masked -- having a getter/setter makes it easier to
enforce the mask.
