msm: ipa3: supporting hibernate & cleanup unused deepsleep API's

Adding changes to listen for new PM driver events to support
hibernate feature. Also, in 5.15 kernel, deepsleep & hibernate
entry/exit SSR API's are becoming same as regular SSR usecases.
So, cleaning up the unused deepsleep API's accordingly.
