[PATCH] drm/i915/dp: use EXPORT_SYMBOL_IF_KUNIT() for kunit helpers

[Jani Nikula <jani.nikula@intel.com>]

Use EXPORT_SYMBOL_IF_KUNIT() instead of the regular EXPORT_SYMBOL() to
export the symbols to the kunit namespace. Otherwise, the symbols get
exported for all the kernel to see, and the corresponding
MODULE_IMPORT_NS("EXPORTED_FOR_KUNIT_TESTING") in the tests is
meaningless.

Fixes: 2eb9982ff179 ("drm/i915/kunit: Export link training and caps funcs for testing")
