Commit 6ae4c3efbd ("ARM: DRA7: Add pinctrl register definitions")

CL-SOM-AM57x board to use these new macros to facilitate the removal
of the old macros.
NOTE:
The PEN and PDIS macro values used previously were actually defined
inversely, a value of 1 in bit position 16 actually means that the
internal pullup/pulldown is disabled and not enabled as inferred by
PEN. So, previous pinmux config data such as (PDIS | PTU) is confusing
as it actually was meant for enabling internal pullup. The data is
fixed up only to be equivalent to the previous data.
