Hans de Goede 8bb58964bc [media] gspca: Add reset_resume callback to all sub-drivers 
1) The gspca-core's suspend/resume code is such that resume being called after
a reset is safe / ok.

2) All devices tested sofar seem to need the reset_resume callback to work
properly over a suspend

3) The USB-core won't call the reset_resume callback for devices which don't
need it

Thus it seems the simplest and the best to just add the callback to all
sub-drivers, rather then adding the callbacks one-by-one as each driver gets
tested with suspend/resume.
