as the fall back compatible.

v11: Add 'Reviewed-by: Krzysztof Kozlowski'

v10: Remove unnecessary ipq5332 constraint in 'power domains' not required
constraint
Fix maxItems for interrupts contstraint of sdm845

v9: Remove superfluous ipq5332 constraint since the fallback is present

v8: Use ipq9574 as fallback compatible for ipq5332 along with ipq5424

v7: Moved ipq9574 related changes to a separate patch
Add 'global' interrupt

v6: Commit message update only. Add info regarding the moving of
ipq9574 from 5 "reg" definition to 5 or 6 reg definition.

v5: Re-arrange 5332 and 9574 compatibles to handle fallback usage in dts

v4: * v3 reused ipq9574 bindings for ipq5332. Instead add one for ipq5332
* DTS uses ipq9574 compatible as fallback. Hence move ipq9574 to be able
to use the 'reg' section for both ipq5332 and ipq9574. Else, dtbs_check
and dt_binding_check flag errors.
