X86_64 allmodconfig screams like so:
warning: (PINCTRL_MT6397) selects PINCTRL_MTK_COMMON
which has unmet direct dependencies
(PINCTRL && (ARCH_MEDIATEK || COMPILE_TEST) && OF)
So add OF to dependencies to shut up this warning.

Add mt6397 support using mediatek common pinctrl driver.
mt6397 is a PMIC, and pinctrl/GPIO is part of 6397 chip.
Pinctrl/GPIO driver should obtain regmap from PMIC,
so adding this support to common code.
Also, mt6397 is no need to support interrupt controller,
so changing common code to skip it.

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.

Add common code mtk_pctrl_spec_pull_set_samereg out of spec_pull_set

Remove them.
Some per-pin data are using int for pin number and offsets.

cppcheck detected an uninitialized variable:
[drivers/pinctrl/mediatek/pinctrl-mtk-common.c:897]:
(error) Uninitialized variable: unmask
unmask should be initialized to zero to ensure unmasking
only occurs if a previous mask occurred. The current situation
is that the unmask variable could contain any random garbage
causing random unexpected unmasking.
