Implement platform driver shutdown callback to perform proper greybus
shutdown so that the userspace unipro_shutdown service that shuts down
the APB/SVC abruptly can be removed. The shutdown callback in
arche-platform will first remove SVC so that all the Interface can be
Deactivated in a sequence according to the spec before powering off the
APB:
Before:
-> Arche/APB power off
-> SoC power off
After this patch:
-> HD shutdown
-> SVC shutdown
-> Module shutdown
-> Interface shutdown
-> Bundle shutdown
-> Arche/APB power off
-> SoC power off
Testing Done:
- Observe all Interfaces are deactivated in the log during shutdown
- Measure power off current and make sure no regression
