Hardware Event Notification Service

A new and independent end-to-end hardware event notification stack is being introduced for sending the various hardware status notifications like camera physical shutter open/close status or microphone cover status (if required). This service is designed generically to send any event notification generated from hardware (via GPIO-based interrupts) all the way to system service. Currently, the scope is limited to reflect the notification status to system settings, but in future releases, it can be extended to send the notification to registered clients too via a custom interface. In the absence of the hardware-based trigger, a software-based trigger (through debugfs) will also be supported to validate the end-to-end functionality of this service.
