Subject: [PATCH 0/3] Introduce Protection Domain Restart (PDR) Helpers

Qualcomm SoCs (starting with MSM8998) allow for multiple protection
domains (PDs) to run on the same Q6 sub-system. This allows for
services like AVS AUDIO to have their own separate address space and
crash/recover without disrupting the other PDs running on the same Q6
ADSP. This patch series introduces pdr helper library and adds PD
tracking functionality for "avs/audio" allowing apr services to register
themselves asynchronously once the dependent PDs are up.
