of/fdt: Fix #ifdef dependency of early flattree declarations
If OF_FLATTREE=y, but OF_EARLY_FLATTREE=n: drivers/tty/serial/earlycon.o: In function `param_setup_earlycon': earlycon.c:(.init.text+0x3a4): undefined reference to `early_init_dt_scan_chosen_stdout' Fix this by moving the early flattree forward declarations and dummy implementations inside an #ifdef CONFIG_OF_EARLY_FLATTREE block.
