power: supply: rt5033_charger: Simplify initialization of rt5033_charger_data

Currently the struct "rt5033_charger_data" is initialized rather complicated.
The cause lies inside of the struct "rt5033_charger", where struct
"rt5033_charger_data" is implemented as a pointer *chg.

Therefore, inside of struct "rt5033_charger" change the struct
"rt5033_charger_data" to non-pointer "chg". It is then initialized right
away and can be accessed more easily.
