Fix the following compile warning:
sound/soc/codecs/wm8731.c:575:12: warning: 'wm8731_request_supplies' defined
but not used [-Wunused-function]
sound/soc/codecs/wm8731.c:600:12: warning: 'wm8731_hw_init' defined but not
used [-Wunused-function]
Signed-off-by: zhong jiang <zhongji...@huawei.com>

v1->v2:
- Move the declaration of wm8731_supply_names into the #if block
unused function has been wrapped to decrease the #if block definition.
