Subject: [PATCH] USB: core: add missing header dependencies

We get 1 warning when building kernel with W=1:
drivers/usb/core/of.c:31:21: warning: no previous prototype for 'usb_of_get_child_node' [-Wmissing-prototypes]

In fact, this function is declared in linux/usb/of.h, so this patch
add missing header dependencies
