kamasali e8b5afb658 ANDROID: vendor_hooks: Add hook for partial_init
Need this vendor hook to support patial init functionality. This hook needs to be restricted as the additional vendor handling need to perform operations (such as wait_for_completion) in non-atomic context.
One of the main functionality of Partial init feature is to reduce latency during resume.
