During SSR, GPR will receive adsp down notification
first and set to SUBSYS_DOWN mode. Sometimes before
audio_prm received adsp down notification, prm_gpr_send_pkt
is called but it will get stucked in spf_core_is_apm_ready
for 30s and device crash happens. In audio_prm, before
checking if spf is ready, check if both prm and gpr are ready
to avoid getting stucked.

Add interface to register callback with adsp loader client.
When adsp is stuck and does not respond for apr_send_pkt,
resulting in continuous EAGAIN error, trigger this
callback to enable adsp subsystem restart.

Add support for virtualized APR frontend driver for audio.
Virtualized APR frontend driver resides in guest VM and
supports all legacy APR APIs. It will rely on MSM_HAB
to communicate with APR backend driver, which resides in
physical VM, where legacy SMD is utilized for communication
between APPS and ADSP.

priority level. Expose an interface from APR layer
so that clients can vote for a priority upgrade
whenever needed.
