V4L: Fix broken TUNER_LG_NTSC_TAPE radio support

The TUNER_LG_NTSC_TAPE is identical in all respects to the
TUNER_PHILIPS_FM1236_MK3. So use the params struct for the Philips
tuner.
Also add this LG_NTSC_TAPE tuner to the switches where radio specific
parameters are set so it behaves like a TUNER_PHILIPS_FM1236_MK3. This
change fixes the radio support for this tuner (the wrong bandswitch byte
was used).

Thanks to Andy Walls <cwalls@radix.net> for finding this bug.
