[Intel-xe] [PATCH 4/7] drm/xe: Use XE_KUNIT for symbol namespace

[Lucas De Marchi <lucas.demarchi@intel.com>]

Instead of simply using EXPORT_SYMBOL() so the functions can be called
across modules, use EXPORT_SYMBOL_NS_GPL() with a private XE_KUNIT
namespace. This avoids accidentally "leaking" these functions and letting
them be called from outside the kunit tests. Use the _GPL() variant
since it's the license declared for the test modules.  If these
functiosn are accidentally called from another module, they would
receive a modpost error like below:

	ERROR: modpost: module XXXXXXX uses symbol
	xe_ccs_migrate_kunit from namespace XE_KUNIT, but does not
	import it.
