Changes in v2 from the cover letter
* Move the stream reset code from flexcop_pci to flexcop_hw_filter so the fact it might interfere with hw_filter code isn't missed.
* Control both streams - so output stream aswell as receive.
* Track the external stream state so we don't leave the stream turned off in a reset.
* Don't let the external control start the stream until a feed is actually requested.

Cover letter [PATCH v2 0/4] SkystarS2 pid filtering fix and stream control
This patch series finishes off the addition of the SkyStarS2 card - the patches here aren't strictly required for running the card so haven't previously been included.
The first patch fixes a bug present in the current flexcop driver - I've seen it with this card, and it has also been noticed in some other cards. Those cards will need identifying and patches created to use this fix as it is not enabled by default.
The other three patches add in a feature that was half complete in the original binary blob for this card, and allows the demod chip to control the streams on the b2c2 when it turns off it's output during tuning. This helps to avoid a situation where the hardware filter is constantly reset by a software watchdog in flexcop-pci because it can't see any data coming in.
Changes since v1:
* Move the stream reset code from flexcop_pci to flexcop_hw_filter so the fact it might interfere with hw_filter code isn't missed.
* Control both streams - so output stream aswell as receive.
* Track the external stream state so we don't leave the stream turned off in a reset.
* Don't let the external control start the stream until a feed is actually requested.
