The interrupt aggregator in DMSS for TI K3 devices currently uses a
custom vendor property "ti,interrupt-ranges" to specify the interrupt
source to parent mapping. As per interrupt controller bindings [1],
it is mandatory for Nodes that describe devices which generate
interrupts to contain an "interrupts" property, an "interrupts-extended"
property, or both. Add interrupts property to the Interrupt aggregator
node so that the mapping is specified in a standard manner.

DONOTMERGE - while adding the interrupts property helps to conform to the
bindings, it is difficult to maintain the long list and this is not the only
platform affected, if this is the direction to fix it, I will fix for all K3
platforms together, more details on RFC in cover letter.
