pinctrl: mxs: avoid defines prefixed with CONFIG

pinctrl: mxs: avoid defines prefixed with CONFIG

Defines prefixed with "CONFIG" should be limited to proper Kconfig options,
that are introduced in a Kconfig file.

Here, expressions to convert pin configurations to booleans for pull-up,
voltage and mA are macro definitions that begin with "CONFIG".

To avoid defines prefixed with "CONFIG", rename these defines to begin with
"PIN_CONFIG" instead.

No functional change.
