This patch adds the missing gpi28 to the list of GPIOs in the GPI P3 "chip".
NOTE: This patch depends on incrementing LPC32XX_GPI_P3_MAX. When applied
without the respective mach-lpc32xx patch (merged via arm-soc.git), gcc will
give a warning about "excess elements in array initializer" but this doesn't
harm.

For GPIOs of gpio-lpc32xx, gpio_direction_output() ignores the value argument
(initial value of output). This patch fixes this by setting the level
accordingly.

Since LPC32xx is now switched over to devicetree based GPIO, the unused
lpc32xx_gpio_init() can be removed.
Further, the driver title changed since it referred to the wrong file.

This patch adds device tree support for gpio-lpc32xx.c.
To register the various GPIO banks as (struct) gpio_chips via the same DT
gpio-controller, we utilize the adjusted of_xlate API to manipulate the
actually used struct gpio_chip.

The chip offers the function to detect the current state of output of the GPO
P3 pins. Useful for reading GPIO output state in Linux' GPIO API, e.g. via
sysfs.
Please note that this only reads back the currently programmed output state,
not the actual electrical level in terms of a GPI function. Finally, GPO3 is
still just an output.
