First set of IIO fixes in the 4.15 cycle.

* kernel-doc
  - fix a build error from symbols ending in _ by making them _*
* cpcap
  - Fix wrong handling of platform_get_irq_by_name which can return a
    postive value on success.
* max30102
  - ABI says temperature should bein milli Celsius after scaling. Here it
    was in Celsius.
* meson-saradc:
  - for Meson8/8b the gate clock bit was wrongly selected due to ffs/fls fun.
  - bandgap was not initialized properly on older socs.  Mostly got away
    with this because the bootloader was doing it for us.
  - Meson8/8b don't have some registers in the general regmap config. Give
    them their own ones.
* stm32-lptimer/stm32-adc trigger
  - Fix a link error when optional stm32-lptimer driver isn't built.
* sx9500
  - we recently removed explict handling of ACPI provided gpio interrupts
    as the core i2c acpi code started providing them directly.  Unfortuantely
    there are ACPI tables out there that use GpioIO resources and it doesn't
    know to map those as interrupts.  As such partial revert the removal
    of this handling from the driver.
