First set of IIO fixes for the 5.4 cycle.

* adis16400
  - Make sure to free memory on a few failure paths.
* adxl372
  - Fix wrong fifo depth
  - Fix wrong indexing of data from the fifo.
  - Perform a reset at startup to avoid a problem with inconsistent state.
* axp288
  - This is a fix for a fix.  The original fix made sure we kept the
    configuration from some firmwares to preserve a bias current.
    Unfortunately it appears the previous behaviour was working around
    a buggy firmware by overwriting the wrong value it had.  Hence
    a regression was seen.
* bmc150
  - Fix the centre temperature.  This was due to an error in one of the
    datasheets.
* hx711
  - Fix an issue where a badly timed interrupt could lead to a control
    line being high long enough to put the device into a low power state.
* meson_sar_adc
  - Fix a case where the irq was enabled before everything it uses was
    allocated.
* st_lsm6dsx
  - Ensure we don't set the sensor sensitivity to 0 as it will force
    all readings to 0.
  - Fix a wait time for the slave i2c controller when the accelerometer
    is not enabled.
* stm32-adc
  - Precursor for fix. Move a set of register definitions to a header.
  - Fix a race when several ADCs are in use with some using interrupts
    to control the dataflow and some using DMA.
* vcnl4000
  - Fix a garbage of_match_table in which a string was passed instead
    of the intended enum.
