First set of IIO and counter fixes for the 5.12 cycle 

adi,ad7949
 * Fix a wrong bitmask that could lead to an undefined bit being included.
 adi,adi-axi-adc
 * Add missing Kconfig dependencies
 adi,adis16400
 * Wrong error code handling in adis16400 that could lead to failed probe.
 hid-sensor-humidity, temperature
 * Fix alignment and space for timestamp channel.
 hid-sensor-prox
 * Fix an issue with handling of exponent on the channel scaling.
 invensense,mpu3050
 * Fix a hole in error handling.
 qcom,spi-vadc
 * Correct scaling
 st,ab8500-adc
 * Fix wrong scaling (by factor of 1000)
 st,stm32-adc
 * Add missing HAS_IOMEM dependency
 st,stm32-timer-cnt
 * Report count when running off internal clock
 * Fix issue with not checking ceiling before trying to write to hardware
 * Ensure driver doesn't have stashed state which doesn't match hardware by
   rereading from hardware in a slow path.
