[PATCH] pinctrl: nomadik: Fix pull direction debug info

[Andrew Halaney <ajhalaney@xxxxxxxxx>]

The nomadik pinctrl hardware doesn't have any way to
determine if the active pull is up or down. Reading
the bit currently used to report if the pull is up/down
indicates if the gpio input is reading high or low, it
doesn't reflect the pull state.

For this reason change the output from "pull up"/"pull down" to
"pull enabled". This avoids confusing developers who were using
the output to determine what the pull state is.
