Subject: [PATCH] mfd: twl-core: remove unused add_child and add_numbered_child functions

drivers/mfd/twl-core.c:654:30: error: unused function 'add_child' [-Werror,-Wunused-function]
static inline struct device *add_child(unsigned mod_no, const char *name,
                             ^
add_numbered_child and its only caller add_child are not used, so remove them.
