Subject: [PATCH 3/3] arm64: dts: ti: k3-pinctrl: Add the remaining macros

Add the drive strength, schmitt trigger enable macros to pinctrl file.
Add the missing macros for deep sleep configuration control.
Reword the existing deep sleep macros to provide combinations that can
directly be used in device tree files.
