[media] dib7000: export just one symbol

Exporting multiple symbols don't work as it causes compilation
breakages, due to the way dvb_attach() works.

This were reported several times, like:

   drivers/built-in.o: In function `cxusb_dualdig4_rev2_tuner_attach':
>> cxusb.c:(.text+0x27d4b5): undefined reference to `dib7000p_get_i2c_master'
   drivers/built-in.o: In function `dib7070_set_param_override':
   cxusb.c:(.text+0x27d5a5): undefined reference to `dib0070_wbd_offset'
>> cxusb.c:(.text+0x27d5be): undefined reference to `dib7000p_set_wbd_ref'
   drivers/built-in.o: In function `dib7070_tuner_reset':
>> cxusb.c:(.text+0x27d5f9): undefined reference to `dib7000p_set_gpio'
   drivers/built-in.o: In function `cxusb_dualdig4_rev2_frontend_attach':
>> cxusb.c:(.text+0x27df5c): undefined reference to `dib7000p_i2c_enumeration'

In this specific report:
	CONFIG_DVB_USB_CXUSB=y
	CONFIG_DVB_DIB7000P=m

But the same type of bug can happen if:
	CONFIG_DVB_DIB7000P=m
and one of the bridge drivers is compiled builtin (cxusb, cx23885-dvb
and/or dib0700).

As a bonus, dib7000p won't be loaded anymore if the device uses
a different frontend, reducing the memory footprint.

Tested with Hauppauge Nova-TD (2 frontends).
