pinctrl: tree-wide probe devices during core_initcall ...

Since commit 37e6bee7e5 ("gpiolib: Add support for GPIO "hog" nodes")
barebox can handle hog-gpios. To work correctly the pinctrl driver
must be initialised first. Reorder all pinctrl drivers so they will be
called first.

pinctrl: imx-iomux-v3: fix compiler warning ...

Fix a warning while compiling with GCC 5.4.0 (OSELAS.Toolchain 2016.02):

    drivers/pinctrl/imx-iomux-v3.c: In function 'imx_iomux_v3_set_state':
    drivers/pinctrl/imx-iomux-v3.c:153:13: warning: 'share_conf_val' may be used uninitialized in this function [-Wmaybe-uninitialized]
        conf_val &= ~IMX_PAD_SION;

we have the pattern:

	if (share_conf)
		share_conf_val = ...;
	...

	if (share_conf)
		use(share_conf_val);

GCC 5.4.0 doesn't recognize this so explicitly initialize
share_conf_val.

pinctrl: i.MX7: Fix LPSR sel_imput setting ...

The i.MX7 has two pinmux controllers, the regular and the LPSR
controller. The LPSR pinmux controller doesn't have any sel_input
registers, instead they can be found in the regular pinmux controller.
This means whenever we want to apply the the sel_input setting for
the LPSR controller, we have to apply them to the regular controller
instead.
In barebox take the easy way out and just add the difference of the
two base addresses to the register offset. The same issue is present
in the Kernel aswell, but when the bootloader already configured
the pins correctly nobody notices when the Kernel sel_input setup
effectively is a no-op.

ARM i.MX: Add i.MX6SL support ...

Most i.MX6SL infrastructure is already covered in barebox by general i.MX6
support. Missing infrastructure provided in separate commits are
* SoC type detection
* Clock infrastructure

Add the missing fsl,imx6sl-mmdc, so it will not be catched by fsl,imx6q-mmdc
and the remaining bits and pieces to provide barebox i.MX6SL SoC support.

driver: replace dev_request_mem_region with dev_request_mem_resource ...

dev_request_mem_region doesn't work properly one some SoCs on which
PTR_ERR() values clash with valid return values from dev_request_mem_region.
Replace them with dev_request_mem_resource where possible.
