[PATCH] of/fdt: hide of_ftd_match() if unused

[Arnd Bergmann <arnd@xxxxxxxx>]

The only caller of this function is built conditionally:

drivers/of/fdt.c:129:19: error: 'of_fdt_match' defined but not used [-Werror=unused-function]

Move the definition into the same #ifdef block.

Fixes: 9b4d2b635bd0 ("of/fdt: Remove dead code and mark functions with __init")
Signed-off-by: Arnd Bergmann <arnd@xxxxxxxx>
