V4L/DVB (5777): Dvb-pll digitv dvb-usb: Eliminate last user of dvb_pll_configure
The last user of dvb_pll_configure was the dvb-usb function dvb_usb_tuner_calc_regs(), which was nothing more than a wrapper around dvb_pll_configure(). It's just a copy of the functionality provided by the tuner_ops calc_regs method, and can be deleted. There were two users of dvb_usb_tuner_calc_regs(). One was dvb_usb_tuner_set_params_i2c(), which is converted to use fe->ops.tuner_ops.calc_regs(). The other was the digitv driver. This driver can use one of two demods, mt352 or nxt6000. For the mt352, the driver would set tuner_ops.calc_regs to dvb_usb_tuner_calc_regs(). We can just attach dvb_pll and use the tuner_ops.calc_regs() provided by that module. For the nxt600, the driver would set tuner_ops.set_params to digitv_nxt6000_tuner_set_params. That function would in turn use dvb_usb_tuner_calc_regs(). We convert it to use tuner_ops.calc_regs() instead, and use dvb_pll_attach. The digitv_tuner_attach() needs to know which frontend was attached by digitv_frontend_attach(), since the nxt6000 needs tuner_ops.set_params() to be overridden with digitv_nxt6000_tuner_set_params(). So, to do this a digitv_state that says which frontend was used is added to the dvb_usb_device private state field.
