[media] r820t: add a commented code for GPIO
Add the code to set the GPIO for this tuner. This code is
currently unused, so it is kept there only for completeness.
With this patch there are just two things that got left from
the original driver:
- At standby, there's another mode, not used by rtl2832u.
Not sure if it might be needed in the future, but I suspect
it is not used at all;
- There is a "fast tune" mode. As nor DVB or V4L API supports
it, it seems an overkill to implement it.
