Ricardo Salveti cf59106433 gpio: stm32: add support for STM32F4
Implements MCU-specific GPIO input interrupt integration.  Added
definition of System configuration controller as well as its needed by
the GPIO code.

The SYSCFG controller is used for system-specific configuration such as:
 - remap the type of memory accessible at address 0x00000000
 - manage the external interrupt line connection to GPIOs
 - configure the I/O compensation cell

Ricardo Salveti a9f2061dfb gpio: stm32: introduce alternative function config
STM32F4 requires the alternative function config to be set, so just
initialize that as part of the gpio configure call.

Tomasz Bursztyka fea1c49ba2 gpio: Improve the public API to handle multi callbacks
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.

Vinicius Costa Gomes d872bb173c pinmux: Move STM32 boards to the pinmux model
This moves the STM32 based boards (Nucleo F103RB and STM32 Mini A15) to
the "new" pinmux model.

Andre Guedes 300bbdc2f4 gpio: Fix returning code from stm32 driver
This patch fixes gpio_stm32 driver since it was merged with a few
occurrences of DEV_* error code.

Maciek Borzecki 1524e713c5 gpio/stm32: GPIO input with interrupts
Add support for interrupts for input GPIO pins on STM32 MCUs. The SoC
support code is expected to provide an implementation of
stm32_gpio_enable_int() call.

Maciek Borzecki 6461e70b72 gpio/stm32: add common driver for STM32 GPIO
The driver implements a GPIO device interface for STM32 MCUs. Each SoC
must provide implementation of the follwoing calls:
stm32_gpio_flags_to_conf(), stm32_gpio_configure(),
stm32_gpio_set(). Consult gpio_stm32.h header for details on semantics
of these calls.

The driver registers 5 devices, each corresponding to a single GPIO
port. The users can then access individual pins by using values
0-15.
