ASoC: SOF: sof-client: Add support for on-demand DSP boot
With the introduction of on-demand DSP boot the rpm status not necessary
tells that the DSP firmware is booted up.
Introduce the sof_client_boot_dsp() which can be used to make sure that
the DSP is booted and it can handle IPCs.
Update the client drivers to use the new function where it is expected that
the DSP is booted up.
