[media] si4713: Remove "select SI4713"

  Commits 7391232e1215 ("[media] si4713: Reorganized drivers/media/radio
directory") and b874b39fcd2f ("[media] si4713: Added the USB driver for
Si4713") both added a "select SI4713". But there's no Kconfig symbol
SI4713, so these selects are nops. It's not clear why they were added
but it's safe to remove them anyway.

USB_SI4713 and PLATFORM_SI4713 both depend on I2C_SI4713. So the select
should be I2C_SI4713. If you can post a patch fixing that, then I'll pick
it up for 3.14.

With the addition of the USB si4713 driver things moved around and were
renamed, and these selects were missed.

Are you sure? I've actually scanned si4713.c before submitting this
patch and I couldn't find anything in it that these other two modules
require. Have I overlooked anything?

The i2c module is loaded by v4l2_i2c_new_subdev_board().

I see. Thanks.

But now I wonder: is I2C_SI4713 useful on itself? Would anyone use
si4713.ko without using either radio-usb-si4713.ko or
radio-platform-si4713.ko? Because it seems that if what people actually
use is radio-usb-si4713.ko or radio-platform-si4713.ko than I2C_SI4713
could be made a 'select only' Kconfig symbol (that won't show up in
menuconfig), couldn't it?

It's possible to create an out-of-tree driver that uses the i2c si4713
driver. So yes, it should be possible to just select the i2c driver without
any of the others.
