[media] stv090x: remove export symbol for stv090x_set_gpio()

Drivers that use dvb_attach can have just one exported symbol,
or they will cause compilation breakages depending on the
selected frontends.

As Jim reported:
drivers/built-in.o: In function `technisat_usb2_set_voltage':
technisat-usb2.c:(.text+0x3b4919): undefined reference to `stv090x_set_gpio'
make: *** [vmlinux] Error 1

That happens because, on his configuration, the configuration
is:

	CONFIG_DVB_USB=y
	CONFIG_DVB_STV090x=m

Luis proposed ar way to fix, but that would just force the
STV090x to be selected, even if one wants to use a device
with a different frontend.

Instead, let's do the right thing: move set_gpio to the
configuration structure and fill it during dvb_attach().

This way, the driver can still call it, and dvb_attach()
will load stv090x module only if the device really needs it.
