[media] saa7134-input: key up events not sent after suspend/resume
On my AverMedia AverTV Studio 507, key up events are no longer sent after
a suspend-to-disk/resume cycle, resulting in "stuck" keys.
Apparently, for key up events to be generated, a certain GPIO pin must be set.
Currently it's set in saa7134_input_init1(), but that function is not called
on device resume. I suggest that code be moved to __saa7134_ir_start(), which
is called both on init and resume.
