Make the support of PMIC peripheral interrupts optional for
spmi-pmic-arb devices. This is useful in situations where
SPMI address mapping is required without the need for IRQ
support.

drivers/spmi/spmi-pmic-arb.c | 45 +++++++++++++++++++++++++++-----------------
Is there a binding update? Can the binding be converted to YAML as well?
This change doesn't add/update any dtsi properties but just checking if an
existing property is present to decide if IRQ support is required, so no
binding change is needed.

I don't think we should be keying off of interrupt-names. Instead we
should be checking for something else. Maybe interrupt-controller
property?
Sure, I can update it to check the presence of "interrupt-controller"
property.
