arm64: dts: qcom: sm8150-kumano: Add GPIO line names for PMIC GPIOs

Sony ever so graciously provides GPIO line names in their downstream
kernel (though sometimes they are not 100% accurate and you can judge
that by simply looking at them and with what drivers they are used).

Add these to the Griffin and Bahamut device trees to better document
the hardware.

They are the same on both devices! Very nice!
