ASoC: wm_adsp: Correct DSP pointer for preloader control

Browse Source 
commit b1470d4ce77c2d60661c7d5325d4fb8063e15ff8 upstream.

The offset of the DSP core needs to be taken into account for the DSP
preloader control get and put. Currently the dsp->preloaded variable
will only ever be read/updated on the first DSP, whilst this doesn't
affect the operation of the control the readback will be incorrect.
