This patch adds a inline dummy implementations of_find_node_by_phandle()
and of_get_next_parent() in "#ifdef CONFIG_OF" else part. Without
this patch,build system can lead to issues. This was discovered during
randconfig testing,in which VEXPRESS_CONFIG was enabled w/o CONFIG_OF
being enabled,leading to the following error:
CC drivers/mfd/vexpress-config.o
drivers/mfd/vexpress-config.c: In function ‘__vexpress_config_func_get’:
drivers/mfd/vexpress-config.c:117:4: error: implicit declaration of function
