MIPS: Netlogic: replace early_init_devtree() call
The early_init_devtree() API was removed in linux-next for 3.13 with commit "mips: use early_init_dt_scan". This causes Netlogic XLP compile to fail: arch/mips/netlogic/xlp/setup.c:101: undefined reference to `early_init_devtree' Add xlp_early_init_devtree() which uses the __dt_setup_arch() to handle early device tree related initialization to fix this.
