IIO: 2nd set of fixes for 6.10

The usual mixed bag of new stuff and long term issues that have surfaced
as a particular driver gets more adoption.

adi,ad7266
- Add missing error check that could lead to bad data being reported.
adi,ad9739a
- Fix Kconfig to not allow COMPILE_TEST to override lack SPI support.
bosch,bme680
- Fix units for pressure value (off by factor of 10)
- Fix sign on a calibration variable read back from the device
- Avoid integer overflow in compensation functions.
- Fix an issue with read sequence that leads to stale data and bad first
  reading.
freescale,fxls8962af
- Kconfig dependency fixes.
ti,hdc3020
- Fix representation of hysteresis to match ABI by being an offset from
  the current event threshold, not an absolute value.
xilinx,ams
- Don't include the ams_ctrl_channels in a computed mask.  This driver is
  making an unusual use of scan_mask (it doesn't support buffers) and that
  lead to an overflow.
