IIO: Fixes for 6.18 (set 1)

The usual mixed back of brand new and ancient bugs.

dmaengine buffer / core
- Add new callback to allow fetching the providing device for a DMA
  channel. Use this to get the right device for the dmaengine buffer
  implementation.
adi,ad4030
- Fix incorrect _scale value for common-mode channels.
adi,ad7124
- Fix gain and offset for temperature channel.
adi,ad7280a
- Fix a factor of 10 error when setting the balance timer.
adi,ad7380
- Fix sampling frequency to account for need to trigger twice per scan
  for some supported chips.
adi,adxl355
- Ensure a long enough wait after SW reset.
bosch,bmc150
- Fix wrong assumption that interrupts are always available.
bosch,bmp280
- Fix the measurement time calculation.
richtek,rtq6056
- Fix wrong sign bit when sign extending.
samsung,ssp
- Fix cleanup of registered mfd devices on error.
st,lsm6dsx
- Fix wrong sized array for register information.
- Fix a wrong time stamp calculation for some devices.
st,stm32-dfsdm
- Update handling of st,adc-alt-channel to reflect binding change as
  part of moving to iio-backend framework.
ti,hdc3020
- Fix wrong units for temperature and humidity. Also the thresholds
  and hysteresis.
