Fix remaining hangs with ARM11 DSP module LLE

[neobrain]

For the most part DSP LLE already works, but I encountered some issues while recording the Mii Maker video that prompted development of DSP HLE. I think Mii Maker itself isn't working with LLE (i.e. it doesn't output any non-zero audio samples to samples.raw).

To switch to LLE, remove this line from os.cpp:

hle_titles["dsp"].create = FakeProcessFactoryFor<FakeDSP>;

You'll also want to run the emulator with the --enable_audio switch.
