[media] em28xx: fix GPIO problem with HVR-900R2 getting out of sync with drx-d
The em28xx bridge strobes the reset pin on the drx-d on every ts_ctrl call.
This results in the state of the chip getting out of the sync with the
state of the driver (and hence all tuning requests after the first one fail).
Make sure the drx-d is not being held in reset, but don't actually perform a
hardware reset on the chip.
The GPIO block has been split out from the other HVR-9x0 variants to reduce
the risk of regression, although in theory they would not have any issues
since none of those cases have the frontend driver managing any internal
state.
