Subject: [PATCH] of: use correct function prototype for of_overlay_fdt_apply()

When CONFIG_OF_OVERLAY is not enabled the fallback stub for
of_overlay_fdt_apply() does not match the prototype for the case when
CONFIG_OF_OVERLAY is enabled. Update the stub to use the correct
function prototype.

Fixes: commit 39a751a4cb7e ("of: change overlay apply input data from unflattened to FDT")
