Input: edt-ft5x06 - move parameter restore into helper

Browse Source 
We need to restore the parameters if we switch between the
factory/work mode and during the resume process if we switched off the
power-supply. Therefore refactor edt_ft5x06_work_mode() and move the
"restore the parameters" into a helper routine so we can reuse it later.
