Subject: [PATCH 5.15 637/917] ARM: dts: stm32: fix STUSB1600 Type-C irq level on stm32mp15xx-dkx

From: Fabrice Gasnier <fabrice.gasnier@...s.st.com>

[ Upstream commit 3d4fb3d4c431f45272bf8c308d3cbe030817f046 ]

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")
