[PATCH 4/5] arm64: dts: apple: t8140: Add pinctrl nodes

[Yureka Lilian]

Add the pin controller nodes present on the Apple Silicon T8140 (A18
Pro) SoC. The pinctrl controllers uses the new apple,t8140-pinctrl
compatible to reflect the requirement for not reading or writing the
registers related to the pins listed in gpio-reserved-ranges.
The pinctrl_ap is a prerequisite for enabling the I2C and PCIe
controllers.
