ARM: dts: qcom: Add PM8941 functions device nodes

Add configuration nodes for following devices:

* GPIO block, with 36 pins
* MPP block, with 8 pins
* Current ADC (IADC)
* Volatage ADC (VADC), with multiple inputs
* Thermal sensor device, which is using on chip VADC
  channel report PMIC die temperature
* Power key device, which is responsible for clean system
  reboot or shutdown
* White LED device
* RTC device
