Subject: [PATCH] ARM: dts: qcom: specify PM8550VE_F temp-alarm ADC channel for
 sun V8

Add properties to the PM8550VE_F spmi-temp-alarm device to specify
it's die temperature ADC channel on Sun power grid V8 boards.  This
ensures that software is able to read it's precise die temperature
instead of estimating it based on the TEMP_ALARM peripheral
over-temperature stage.
