Subject: [PATCH 0/2] slimbus: qcom-ngd: Add SSR and PDR support

Qualcomm DSPs support SSR(Subsystem Restart) and PDR(Protection Domain Restart)
which usually restart the associated services!
Current code does only relies on QMI channel notifications, but there could be
race conditions between QMI notifcations and actual PDR/SSR events.

This patchset adds support to these two events to address those race conditions.

Tested it on Dragon Board DB845c.
