[PATCH] media: usb: dvb-usb: fix DIBUSB_MB usage of dib3000mc functions

[Randy Dunlap]

From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

The problem is that this driver uses a "common" driver supplement
which calls a few dib3000mc*() functions but that driver is not
"select"ed by DVB_USB_DIBUSB_MB. We can fix the build errors by
selecting DVB_DIB3000MC (at the expense of around 8 KB on x86_64)
just to add a few "library-like" functions.

Or someone can split the required functions into a separate
buildable file, but for such an ancient driver, I don't see the
need to do this.

Fixes these build errors:

drivers/built-in.o: In function `dibusb_dib3000mc_frontend_attach':
(.text+0x1a63bd): undefined reference to `dib3000mc_pid_parse'
drivers/built-in.o: In function `dibusb_dib3000mc_frontend_attach':
(.text+0x1a63c5): undefined reference to `dib3000mc_pid_control'
drivers/built-in.o: In function `dibusb_dib3000mc_tuner_attach':
(.text+0x1a6610): undefined reference to `dib3000mc_set_config'
