drm/selftests: reduce stack usage
Putting a large drm_connector object on the stack can lead to warnings
in some configuration, such as:
drivers/gpu/drm/selftests/test-drm_cmdline_parser.c:18:12: error: stack frame size of 1040 bytes in function 'drm_cmdline_test_res' [-Werror,-Wframe-larger-than=]
static int drm_cmdline_test_res(void *ignored)
Since the object is never modified, just declare it as 'static const'
and allow this to be passed down.
Fixes: b7ced38916 ("drm/selftests: Add command line parser selftests")
