Jon Medhurst e7391e3068 gpio: Add gpio_mmio32 driver to access basic 32-bit i/o registers
It is envisaged that this will be used by SoC or board code to make
available fixed purpose memory-mapped i/o registers to the rest of the
system which normally expects to use GPIO devices, e.g. for driving chip
select lines, LEDs or reading button states.

As such, the driver code doesn't provide a kconfig based configuration
mechanism, instead SoC/board code can hard-wire the devices it wants
with something simple like:

GPIO_MMIO32_INIT(misc_reg1, "MISC1", 0x12345678, 0xffffffffu)

Then, for example, if bit N of the register at 0x12345678 is wired up as
an SPI device chip select line, the SPI driver could be configured to
use pin N of the "MISC1" GPIO driver and not need any other board
specific code.

Florian Vaussard 52d663d49d gpio: stm32: Use macro to simplify registration
The registration of each GPIO bank differs by only few details. These
differences can be factorized in order to create a generic registration
macro.

This has several advantages:
- Less code
- Easier to add new banks
- Less work to add support for new STM32 families

Paul Sokolovsky 203dec3b69 gpio: mcux: Revert to older GPIO device names as were used for Kinetis.
These are more consistent with naming used by other ports (uppercase,
short), and some existing software relies on them to be exactly those.
This change is a follow up to the discussion on the Zephyr mailing
list, calling to establish consistent naming conventions for Zephyr
devices, and is a small step in that direction.

Iván Briano 867e61cbf3 drivers gpio: Fix disabling of interrupts for QMSI shims
When a GPIO pin is configured, the shim driver will first read the
current values in the controller registers to keep the other pins from
changing their configuration. After that it sets the bits for the
corresponding pin accordingly.

When the flag to enable interrupts is passed to the function, the
corresponding bits are all set properly, but no changes are made if
interrupts are not requested. This makes it impossible to disable
interrupts for a given pin once they've been enabled.

Fix it by always resetting the interrupt enabled bit when they have not
been requested. Other values can be left untouched as they won't have
any effect.
