[PATCH] drm/fbdev: Replace __MODULE_STRING() with __stringify()

[Sasha Levin <sashal@kernel.org>]

Commit 08abfa5a161e ("drivers: Replace __MODULE_STRING() with
__stringify()") converted the drm_fbdev_overalloc parameter description
in drm_fb_helper.c ahead of the removal of __MODULE_STRING().

Commit 6b5a66fd9f21 ("drm/fbdev: Move fbdev module parameters next to
module init") moved that parameter into drm_kms_helper_common.c while it
still used __MODULE_STRING(), so the conversion never reached the moved
code. drm_kms_helper_common.c is now the last user of the macro, and
removing the macro breaks the build with CONFIG_DRM_FBDEV_EMULATION=y:

  drivers/gpu/drm/drm_kms_helper_common.c:46:18: error: expected ')' before '__MODULE_STRING'

Use __stringify() instead. The parameter description is unchanged.

This depends on 6b5a66fd9f21 in drm-next and 08abfa5a161e in
modules-next, both queued for 7.4. Petr plans to remove
__MODULE_STRING() once his conversions are in mainline, so this needs to
land first, either through drm-misc after 7.4-rc1 or together with the
removal patch.

Build-tested on next-20261022 (x86_64, gcc) with __MODULE_STRING()
removed from module.h. The parameter description in modinfo is
unchanged.
