Subject: [PATCH v2 02/11] DONOTMERGE: arm64: dts: ti: Add pinmux and irq mapping for TPS65219 external interrupts

Interrupt occurring on PMIC TPS65219 is propagated to SOC
through EXTINTn pin connected to gic500 interrupt controller

Needed for driver testing but official board support pending.
TI commitment is required before board upstream kick-off.
