input: touchscreen: mms128: remove global variable "enable"

If disable CONFIG_TIZEN_WIP, This driver not work after supend/resume.
Because this driver use variable "enable" and "info->enable" sepearately.
So this patch remove variable "enable" and then, use "info->enable".
Also this patch revise that state is changed at mms_ts_power() only.
