John Crispin 25afe99b31 mediatek: add support for the new MT7623 Arm SoC 
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 52/76] pinctrl: mediatek: add ies/smt control to common code.
Input enable and smt setting have different register,
modify code to fix it.
Several mediatek soc use similar input enable/smt setting
procedure as mt8173, some soc use generic input enable/smt
setting, some soc has no input enable/smt setting. Adding
common code to handle all those cases, so future soc driver
can use it.
