Subject: [PATCH] ARM: dts: stm32: fix STUSB1600 Type-C irq level on stm32mp15xx-dkx

STUSB1600 IRQ (Alert pin) is active low (open drain). Interrupts may get
lost currently, so fix the IRQ type.

Fixes: 83686162c0eb ("ARM: dts: stm32: add STUSB1600 Type-C using I2C4 on stm32mp15xx-dkx")

Applied on stm32-next.
