The settings in the Genesys_Frontend structs go to the analog frontend
via the serial interface at registers 0x3a/0x3b(FEWRDATA)+0x51(FEWRA),
through sanei_genesys_fe_write_data.

If you are receiving noise data, this may indicate that the byte order
was swapped. You should check that the parallel interface to the
frontend is setup correctly(registers 0x52 to 0x57).
