Many sub-systems might require to set a callback on different pins.
Thus enabling it via changing the API.
It is also possible to retrieve private-data in the callback handler
using CONTAINER_OF() macro (include/misc/util.h).
Former API is still available, and is emulated through the new one.
Using both should not be a problem as it's using new API calls.
However, it's now better to start using the new API.

The base address and IRQ line are static per SoC, so there is no need
to make them configurable in Kconfig.

Added device power management hook infrastructure. Added
DEVICE_INIT_PM and SYS_INIT_PM macros that creates device
structures with the supplied device_ops structure containing
the hooks.
Added example support in gpio_dw driver. Updated the sample
app and tested using LPS and Device Suspend Only policies.

This patch replaces all occurences of the macro DEV_INVALID_OP by
-ENOTSUP at the driver level. So this patch touch the files under
drivers/, include/ and samples/drivers/ when applicable.
This patch is part of the effort to transition from DEV_* codes to
errno.h codes.

Interrupt and callback function support is added to the K64F GPIO driver.
The implementation is based on the Designware GPIO driver (gpio-dw.*).

K64 pinmux support is created as a normal driver.
As opposed to the Galileo board, the pin configuration options are
defined by the MCU and are not board-specific. Separate
platform/board-specific configuration code uses the pinmux driver for
the default pin settings. For FRDM-K64F, only the Arduino pins (22 of a
possible 160) are set up.
Some of the I/O pins routed to the Arduino header are also configured as
JTAG/SWD signals by default and are used by the OpenSDAv2 debug
interface. Therefore, a PRESERVE_JTAG_IO_PINS config option was created
for the FRDM-K64 platform to prevent the default pin settings from
re-configuring these pins.
The K64 MCU separates pin configuration and control, implemented in the
pinmux driver, from GPIO. This results in some cross referencing
between the K64 GPIO driver and the K64 pinmux driver due to the
dependencies of one on the other.
This pinmux driver also uses the expanded pinmux function/mode parameter
size to describe pin configuration options with bit fields for the K64,
including up to 8 pin functions, plus interrupt, pullup/down, drive
strength, open-drain and slew rate.
The following GCC warnings in the K64 pinmux driver are prevented when not
compiling with 'no-optimization' (-O0):
warning: 'gpio_dev' may be used uninitialized in this function
[-Wmaybe-uninitialized]

Basic driver support for the Freescale K64 GPIO module.
Note that only pin direction, read and write are supported.
