[ Upstream commit 7687c66c18c66d4ccd9949c6f641c0e7b5773483 ]

If the <kunit/platform_device.h> header is included in a test without certain other headers, it produces compiler warnings like:

In file included from [...] ../include/kunit/platform_device.h:15:57: warning: ‘struct completion’ declared inside parameter list will not be visible outside of this definition or declaration 15 | struct completion *x); | ^~~~~~~~~~

Add a 'struct completion' forward declaration to resolve this.
