firmware: cs_dsp: Introduce no_core_startstop for self-booting DSPs

There are devices containing Halo Core DSPs that self-boot, cs_dsp is
used to manage the running firmware but the host does not have direct
control over starting and stopping the DSP and so cs_dsp should consider
the DSP to be always running.
