V4L/DVB (5978): tuner: Better tuner radio support
Add radio support for the Thomson DTT7612 tuner. This tuner uses a different 1st intermediate frequency than the other radio tuners supported (a lot of NTSC radio tuners probably need this change too). Add a new tuner-simple parameter, radio_if. It selects the 1st IF used for radio reception. The radio frequency setting code in tuner-simple now uses this field, instead of a special case select() block for each tuner with radio support. The tuner parameters for tuners that used a 33.3 MHz RIF now set radio_if to 1 in tuner-types.c. The Thomson DTT7612 gets radio_if = 2, also add has_tda9887 = 1 and fm_gain_normal = 1. Add some defines for tda9887 bits that control IF setting in radio mode. Add a new tda9887 config option, TDA9887_RIF_41_3, that selects a 41.3 MHz radio IF. Fix the way tda9887 radio options work. The driver was modifying the default radio mode config templates based on the TDA9887_XXXX flags. This means that _all_ tuners would get the same settings. If you had a one tuner than used TDA9887_GAIN_NORMAL and one that didn't, both would get the setting. Now the tda9987 driver just checks if tuner mode is radio and then applies the config settings directly to the data being sent, just like how all the TV mode settings already work. The PLL setting math is made a little more accurate. And a grammar error in a printk is fixed.
