This series adds LTC2499 support on top of the existing LTC2497 driver.

It includes:
- a small binding title correction for LTC2499,
- the LTC2499 internal temperature channel,
- the LTC2499 2x conversion speed mode exposed via sampling_frequency.

Validation performed on Raspberry Pi 4 hardware with an DC1012A-A board:
- temperature raw/scale/offset read correctly,
- voltage channels remain sane after temperature reads,
- sampling_frequency 1x/2x switching works,
- pyadi-iio LTC2499 validation passed.
