[PATCH -next] power/supply/cw2015: Make some symbols static

[ChenTao]

Fix the following warning:

drivers/power/supply/cw2015_battery.c:96:5: warning:
'cw_update_profile' was not declared. Should it be static?
drivers/power/supply/cw2015_battery.c:712:1: warning:
'cw_bat_pm_ops' was not declared. Should it be static?
