V4L/DVB: cx25840/ivtv: replace ugly priv control with s_config
The cx25840 used a private control CX25840_CID_ENABLE_PVR150_WORKAROUND to be told whether to enable a workaround for certain pvr150 cards. This is really config data that it needs to get at load time. Implemented this in cx25840 and ivtv.
