[PATCH AUTOSEL 6.12 4/8] kunit: platform: Resolve 'struct completion' warning

[Sasha Levin]

From: Brian Norris <briannorris@chromium.org>

[ 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.
