Devin Heitmueller 11fc9a4a44 V4L/DVB (9316): s5h1411: Power down s5h1411 when not in use
Power down the s5h1411 demodulator when not in use (on the Pinnacle 801e, this
brings idle power from 123ma down to 84ma).

Devin Heitmueller 50eac6bc46 V4L/DVB (9315): s5h1411: Skip reconfiguring demod modulation if already at the desired modulation
If we are already at the desired modulation, there is no need to reconfigure
the demod (at a tuning time cost)

Note that this change revealed that although the datasheet says the demod
starts out in VSB-8 mode, the first tuning was failing consistently unless
we went through the work of setting the registers.  So add a field to denote
this case so we always do the enable_frontend call, even if the first tuning
request is for VSB-8.

Devin Heitmueller f0d041e50b V4L/DVB (9314): s5h1411: Perform s5h1411 soft reset after tuning
If you instruct the tuner to change frequencies, it can take up to 2500ms to
get a demod lock.  By performing a soft reset after the tuning call (which
is consistent with how the Pinnacle 801e Windows driver behaves), you get
a demod lock inside of 300ms
