FROMLIST: arm64: dts: qcom: lemans-pmics: Add ADC support for PMM8654au

Add ADC nodes for the four PMM8654au PMICs (pmm8654au_0 through
pmm8654au_3) on the Lemans platform.

Each ADC node exposes the following ADC channels:
- DIE_TEMP: PMIC die temperature channel
- VPH_PWR: Battery/supply voltage channel

Also add the io-channels and io-channel-names properties under
the temp-alarm nodes so that they can get temperature reading
from the ADC die_temp channels.
