ipq40xx: fix AVM NAND caldata extraction

The AVM Fritz!Box 7530 (and probably other AVM IPQ4019 NAND devices)
has it's caldata not stored consistently, but instead at currently
3 known possible offsets.

As we get a non-zero exit code from fritz_cal_extract, simply try all
three possible offsets on both bootloader partitions, until a matching
caldata for each radio is found.
