Add SPMI GPIO compatible strings for the PMAU0102 and PMM8650AU PMICs used on Nord, each with 12 GPIOs, so the driver can bind against the new per-chip PMIC dtsi nodes. Signed-off-by: Dhruvin Rajpura <drajpura@qti.qualcomm.com>
PMAU0102 and PMM8650AU are new PMICs used on nord-rrd and nord-ride-sx that are not present on lemans/monaco, so there is no existing dtsi to reuse. Add per-chip PMIC dtsi files (pmau0102-nord.dtsi, pmm8650au-nord.dtsi) with their peripheral definitions (temp-alarm, pon, rtc, gpio), matching the hardware-per-file convention used for other PMICs. Update the spmi_bus controller node in nord.dtsi accordingly and switch nord-rrd.dts/nord-ride-sx.dts to include the new per-chip dtsi files.

Add REF_GND, 1P25VREF, VREF_VADC and DIE_TEMP ADC5 Gen3 channels for all PMAU0102 PMIC instances (pmau0102_e through pmau0102_l) and both PMM8650AU PMIC instances (kobra_mm_a and kobra_psail_b), following the existing adc@8000 node convention used for other PMICs in this tree.

Add the OFFSET_REF (REF_GND), 1P25VREF, VREF_VADC and DIE_TEMP ADC5
Gen3 channels for all PMAU0102 PMIC instances (pmau0102_e through
pmau0102_l) and both PMM8650AU PMIC instances (kobra_mm_a and
kobra_psail_b).
Each PMIC instance gets a new adc@8000 node with these four channels,
following the existing adc@8000 node convention used for other PMICs
in this tree (e.g. lemans-pmics.dtsi, monaco-pmics.dtsi).
This is stacked on top of "arm64: dts: qcom: nord: add PMAU0102 and
PMM8650AU PMIC support".
