The syscon header uses the ENOTSUPP error constant, but doesn't
include the header that defines it. This causes a build error
after the imx pinctrl driver started using syscon:
include/linux/mfd/syscon.h: In function 'syscon_node_to_regmap':
include/linux/mfd/syscon.h:32:18: error: 'ENOTSUPP' undeclared (first use in this function)
return ERR_PTR(-ENOTSUPP);
^~~~~~~~
This adds the missing #include.
