the support is still WIP. next steps are to make the pmic and ethernet work.
this is the first commit to make sure nothing gets lost.

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