1st set of IIO fixes for the 5.19 cycle.

Most of these have been in next for a long time. Unfortunately there
 was one stray patch in the branch (wasn't a fix), so I've just rebased
 to remove that.
 
 * testing
   - Fix a missing MODULE_LICENSE() warning by restricting possible build
     configs.
 * Various drivers
   - Fix ordering of iio_get_trigger() being called before
     iio_trigger_register()
 * adi,admv1014
   - Fix dubious x & !y warning.
 * adi,axi-adc
   - Fix missing of_node_put() in error and normal paths.
 * aspeed,adc
   - Add missing of_node_put()
 * fsl,mma8452
   - Fix broken probing from device tree.
   - Drop check on return value of i2c write to device to cause reset as
     ACK will be missing (device reset before sending it).
 * fsl,vf610
   - Fix documentation of in_conversion_mode ABI.
 * iio-trig-sysfs
   - Ensure irq work has finished before freeing the trigger.
 * invensense,mpu3050
  - Disable regulators in error path.
 * invensense,icm42600
   - Fix collision of enum value of 0 with error path where 0 is no match.
 * renesas,rzg2l_Adc
   - Add missing fwnode_handle_put() in error path.
 * rescale
   - Fix a boolean logic bug for detection of raw + scale affecting an
     obscure corner case.
 * semtech,sx9324
   - Check return value of read of pin_defs
 * st,stm32-adc:
   - Fix interaction across ADC instances for some supported devices.
   - Drop false spurious IRQ messages.
   - Fix calibration value handling.  If we can't calibrate don't expose the
     vref_int channel.
   - Fix maximum clock rate for stm32pm15x
 * ti,ads131e08
   - Add missing fwnode_handle_put() in error paths.
 * xilinx,ams
   - Fix variable checked for error from platform_get_irq()
 * x-powers,axp288
