* Adds a new parameter, 'lower_ringing_noise', to module xpd_fxs.
* Makes the "power-down" behaviour that was added
in upstream svn r10478, switchable in runtime.
* By default (false), makes the vbat_h behave like it did
before the power-down change.
- I.e: vbat_h is held throughout the ringing period (during
both ring-up/ring-down)
- So this patch revert part of r10478
* When switched to true, activate the "power-down" behaviour.
- I.e: vbat_h follows the ring-up/ring-down.
- This behaviour lowers the noise caused by group ringing of
FXS channels in the same unit, but causes problems with CallerID.
