ASoC: SOF: add flag to disable IMR restore to sof_debug

Browse Source 
Add flag _IGNORE_D3_PERSISTENT to disable IMR restore feature to
the sof_debug module parameter.

The IMR restore feature will be enabled for all Intel cAVS platforms by
default, but setting the flag _IGNORE_D3_PERSISTENT can help to disable
the feature for debug purpose, to rule out any possible regression
introduced by the change of not re-downloading firmware to the DSP at
resuming from suspended state.
