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);
