V4L/DVB: cx25840/ivtv: replace ugly priv control with s_config

Browse source 
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.

/* pvr150_workaround activates a workaround for a hardware bug that is
present in Hauppauge PVR-150 (and possibly PVR-500) cards that have
certain NTSC tuners (tveeprom tuner model numbers 85, 99 and 112). The
audio autodetect fails on some channels for these models and the workaround
is to select the audio standard explicitly. Many thanks to Hauppauge for
providing this information.
This platform data only needs to be supplied by the ivtv driver. */
