V4L/DVB: ir-core: Add callbacks for input/evdev open/close on IR core
Especially when IR needs to do polling, it generates lots of wakeups per
second. This makes no sense, if the input event device is closed.
Adds a callback handler to the IR hardware driver, to allow registering
an open/close ops.
