This switches the two members of struct gpio_chip that were
defined as unsigned foo:1 to bool, because that is indeed what
they are. Switch all users in the gpio and pinctrl subsystems
to assign these values with true/false instead of 0/1. The
users outside these subsystems will survive since true/false
is 1/0, atleast we set some kind of more strict typing example.

GENERIC_GPIO has been made equivalent to GPIOLIB in architecture code
and all driver code has been switch to depend on GPIOLIB. It is thus
safe to have GENERIC_GPIO removed.

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.

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.
