ARM: dts: exynos: correct PMIC interrupt trigger level on Artik 5

stable inclusion
from stable-5.10.20
commit 83830e692f28f02b75015c924d00dfe30fa0558a
bugzilla: 50608

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

[ Upstream commit cb313346 ]

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.
