Katsuhiro Suzuki 0f408ce894 media: dvb-frontends: add Socionext MN88443x ISDB-S/T demodulator driver
This patch adds a frontend driver for the Socionext/Panasonic
MN884434 and MN884433 ISDB-S/T demodulators.

The maximum and minimum frequency of MN88443x comes from
ISDB-S and ISDB-T so frequency range is the following:
  - ISDB-S (BS/CS110 IF frequency, Local freq 10.678GHz)
    - Min: BS-1: 1032MHz
    - Max: ND24: 2070MHz
  - ISDB-T
    - Min: ch13: 470MHz
    - Max: ch62: 770MHz
