GlassOnTin 5d2f0b93e3 Fix SX1262 errata 15.4 (IQ polarity) and 15.1 (modulation quality) ...

Errata 15.4: SetPacketParams resets register 0x0736 to an incorrect
default for IQ polarity. For standard IQ (no inversion), bit 2 must
be SET after every SetPacketParams call. Without this, LoRa RX
demodulation can fail silently while TX continues to work — the
symptom mimics a hardware failure.

Errata 15.1: Register 0x0889 bit 2 controls modulation quality at
different bandwidths. It must be cleared for 500 kHz BW and set for
all others. The previous implementation was a no-op stub.

Both fixes are from the SX1262 datasheet errata (DS_SX1261-2_V2.1)
and apply to all SX1262-based boards.
