Now that we have a proper pinctrl driver for the gpio block we
can change the compatible field here and configure the pinmux on
msm8960 devices.

The micrel ks8851 device is present on MSM8960 CDP boards. It is
connected to two regulators, one controlled via a gpio and
another controlled via the RPM. Add the gsbi, spi, gpio
regulator, and micrel ks8851 nodes so that ethernet works
properly.
