Subject: [PATCH v2 3/3] arm64: dts: ti: k3-pinctrl: Add the remaining macros
Add the drive stregth, schmitt trigger enable macros to pinctrl file.
Add the missing macros for DeepSleep configuration control referenced
from "Table 14-6172. Description Of The Pad Configuration Register Bits"
in AM625 TRM[0].
Add some DeepSleep macros to provide combinations that can be used
directly in device tree files example PIN_DS_OUTPUT_LOW that
configures pin to be output and also sets its value to 0.
