ARM: dts: exynos: correct PMIC interrupt trigger level on Spring

stable inclusion
from stable-5.10.20
commit 41461029703e62b1612456fedafa5a2b586a15dc
bugzilla: 50608

--------------------------------

[ Upstream commit 77e6a546 ]

The Samsung PMIC datasheets describe the interrupt line as active low
with a requirement of acknowledge from the CPU.  Without specifying the
interrupt type in Devicetree, kernel might apply some fixed
configuration, not necessarily working for this hardware.
