    pinctrl: intel: fix build warnings about export.h

    After commit a934a57 ("scripts/misc-check: check missing #include
    <linux/export.h> when W=1") and 7d95680 ("scripts/misc-check:
    check unnecessary #include <linux/export.h> when W=1"), we get some build
    warnings with W=1:

    pinctrl-intel.c: warning: EXPORT_SYMBOL() is used, but #include <linux/export.h> is missing

    So fix these build warnings for the driver code.
