pinctrl: imx-iomux-v2: correct names in EXPORT_SYMBOL macros ...

The functions have been renamed, but this has not been reflected in the
EXPORT_SYMBOL macros. Do that now.

Fixes several errors like this:
drivers/pinctrl/imx-iomux-v2.c:61:15: error:
	'mxc_iomux_mode' undeclared here (not in a function)
 EXPORT_SYMBOL(mxc_iomux_mode);

of: use 'const void *' for struct of_device_id.data ...

Since 2011 barebox' of_device_id struct uses unsigned long type for data field:

    struct of_device_id {
            char *compatible;
            unsigned long data;
    };

Almost always struct of_device_id.data field are used as pointer
and need 'unsigned long' casting.

E.g. see 'git grep -A 4 of_device_id drivers/' output:

    drivers/ata/sata-imx.c:static __maybe_unused struct of_device_id imx_sata_dt_ids[] = {
    drivers/ata/sata-imx.c- {
    drivers/ata/sata-imx.c-         .compatible = "fsl,imx6q-ahci",
    drivers/ata/sata-imx.c-         .data = (unsigned long)&data_imx6,
    drivers/ata/sata-imx.c- }, {

Here is of_device_id struct in linux kernel v4.0:

    struct of_device_id {
            char name[32];
            char type[32];
            char compatible[128];
            const void *data;
    };

Changing of_device_id.data type to 'const void *data' will increase
barebox' linux kernel compatibility and decrease number of 'unsigned
long' casts.

Part of the patch was done using the 'coccinelle' tool with the
following semantic patch:

    @rule1@
    identifier dev;
    identifier type;
    identifier func;
    @@

pinctrl: remove unnecessary error check ...

The file drivers/pinctrl/pinctrl.c is compiled only when
CONFIG_PINCTRL is defined.  "IS_ENABLED(CONFIG_PINCTRL)" is
always evaluated as 1 in this function.
(Although the compiler would optimize it, the source file does
not look nice.)

pinctrl: fix Kconfig dependencies ...

- Remove OFDEVICE dependency from PINCTRL. It won't do
  much then, so add a comment to Kconfig when PINCTRL is
  selected without OFDEVICE
- Let Architectures only select PINCTRL instead of the
  particular driver. Change the drivers to 'default y if $SOC'
  to make sure the drivers are still compiled if the corresponding
  SoC is selected

This fixes Kconfig warnings like:

warning: (PINCTRL_ARMADA_370 && PINCTRL_ARMADA_XP && PINCTRL_DOVE && PINCTRL_KIRKWOOD) selects PINCTRL which has unmet direct dependencies (OFDEVICE)
