[PATCH -next] drivers: base: swnode: Make two functions static

[Yue Haibing]

From: YueHaibing <yuehaib...@huawei.com>

Fix sparse warning:

drivers/base/swnode.c:475:22: warning: symbol 'software_node_get_parent' was 
not declared. Should it be static?
drivers/base/swnode.c:484:22: warning: symbol 'software_node_get_next_child' 
was not declared. Should it be static?
