Now fixed regulators that have their enable pin connected to a GPIO line
can use the fixed regulator driver for regulator enable/disable control.
The GPIO number and polarity information is passed through platform data.
GPIO enable control is achieved using gpiolib.

This patch adds support for fixed regulators. This class of regulator is
not software controllable but can coexist on machines with software
controlable regulators.
