[PATCH] DVB: frontend updates

- [DVB] all: replace dvb_unregister_frontend_new() with
  dvb_unregister_frontend()

- [DVB] sp887x: fix firmware download, patch by Jose Alberto Reguero

- [DVB] tda1004x: add firmware loading via firmware_class()

- [DVB] dvb_frontend: without hierachical coding, code_rate_LP is
  irrelevant, so we tolerate the otherwise invalid FEC_NONE setting

- [DVB] ves1x93: fixed dropouts on older DVB cards, fix tuning issues
  (Andreas Share / Gregoire Favre),
