   4 Subject: [PATCH 50/76] pinctrl: mediatek: data struct optimize and remove
   5  unused member
   6
   7 struct mtk_desc_pin.chip, mtk_pinctrl_devdata.invser_offset
   8 and mtk_pinctrl_devdata.chip_type are never used in code.
   9 Remove them.
  10
  11 Some per-pin data are using int for pin number and offsets.
  12 Change to short and rearrange to reduce const data size.
