arm64: dts: qcom: hamoa-pmics: Add ADC support

Add ADC node and define channels for:
- Die temperature for PMK8550, PM8550VE* and PMC8380* PMICs.
- PM8550: Die temperature, VPH power, and system thermistors.

Add io-channels and io-channel-names properties to the
temp_alarm nodes so that they can get temperature reading
from the ADC die_temp channels.

Remove die_temp channel of PMC8380_6 for Purwa boards where
this PMIC is not present.
