arm64: dts: exynos: correct PMIC interrupt trigger level on Espresso

stable inclusion
from stable-5.10.20
commit 587b9cc3c02d2de6552f684147e9904e8b0fd0ef
bugzilla: 50608

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

[ Upstream commit 1fea2eb2 ]

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.
