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.

This can be moved below WKUP_ENABLE macro to be consistent
Moved. Thanks

These can be moved to the top before PIN_* and can be renamed to

As EDGE wake is used commonly we can use the PIN_WKUP_EN_EDGE in this case
That's a good idea. Changed.
