[PATCH] dvb: lgdt330x frontend: some bug fixes & add lgdt3303 support

- Structural changes within lgdt330x driver, framework now supports
  both chips... tested OK on lgdt3302 and lgdt3303.
- Add LG/TUA6034 dvb_pll_desc for ATSC with LG TDVS-H062F & DViCO FusionHDTV5.
- Fixed LGDT330X signal strength: For now, always set it to 0.
- Corrected LGDT330X boundary condition error in read_snr: dB calculation.
