dt-bindings: pinctrl: pinctrl-single: fix schmitt related properties

The "pinctrl-single,input-schmitt" have four arguments in the bindings
but the driver needs two. According to the meaning of other properties
and driver, it should have "enable" suffix. Fortunately, there is no
dts using this property, so it is safe to correct this property with the
right name.

Rename existed property "pinctrl-single,input-schmitt" to
"pinctrl-single,input-schmitt-enable" and add the right description for
property "pinctrl-single,input-schmitt" used by the driver.
