581f84e24b mxc: iomuxv1: Do not use gpio_request when setting the pin as GPIO
When setting the IOMUX of multiple pins via mxc_gpio_setup_multiple_pins, gpio_request
is called and this prevents subsequent calls of gpio_request done by drivers to succeed.

Remove gpio_request call from mxc_gpio_setup_multiple_pins function.

As gpio_request is removed from mxc_gpio_setup_multiple_pins, there is no need to have
mxc_gpio_release_multiple_pins anymore, so remove this function.

Tested on a mx27_3ds board and after applying this patch it is possible to define all the
IOMUX setup in a static array

ff255feba1 ARM i.MX: iomux v1 initialization away from initcall
This saves us from soc level dispatching in generic files

bac3fcfad5 arm/imx/iomux-v1: check for invalid modes in mxc_gpio_mode
mxc_gpio_mode checks for invalid pins and so it returns zero for
success, -EINVAL for invalid pins.

While at it, remove definitions of GPIO_PORT_MAX removed as they are
unused now.

111588f830 arm/imx/iomux-v1: rename header file
Addionally make iomux-mx*.h headers stand-alone and similar to iomux-v3
platform files should include their platform iomux header from now on.
For now iomux.h simply includes all iomux-v1 platform headers and so
provides compatibility until all files are converted.

f021b5a1ef arm/imx/iomux-v1: make base address a runtime choice
While at it move register modification to static inlines and
so make the relevant code more readable.
