This patch is in preparation for adding EINT support to MT7622 pinctrl,
and the refactoring doesn't alter any existent logic.
A reason we have to refactor EINT code pieces into a generic way is that
currently, they're tightly coupled with a certain type of MediaTek pinctrl
would cause a grown in a very bad way as there is different types of
pinctrl devices getting to join.
Therefore, it is an essential or urgent thing that EINT code pieces are
refactored to eliminate any dependencies across GPIO and EINT as possible.
Additional structure mtk_eint_[xt, hw, regs] are being introduced for
indicating how maps being designed between GPIO and EINT hw number, how to
set and get GPIO state for a certain EINT pin, what characteristic on a
EINT device is present on various SoCs.

Add support for pinctrl on MT7622 SoC. The IO core found on the SoC has
the registers for pinctrl, pinconf and gpio mixed up in the same register
range. However, the IO core for the MT7622 SoC is completely distinct from
anyone of previous MediaTek SoCs which already had support, such as
the hardware internal, register address map and register detailed
definition for each pin.
Therefore, instead, the driver is being newly implemented by reusing
generic methods provided from the core layer with GENERIC_PINCONF,
GENERIC_PINCTRL_GROUPS, and GENERIC_PINMUX_FUNCTIONS for the sake of code
simplicity and rid of superfluous code. Where the function of pins
determined by groups is utilized in this driver which can help developers
less confused with what combinations of pins effective on the SoC and even
reducing the mistakes during the integration of those relevant boards.
As the gpio_chip handling is also only a few lines, the driver also
implements the gpio functionality directly through GPIOLIB.

Do not hide pinctrl drivers for Mediatek platforms using
conditionals. Doing so actually leaves the symbols present (but
always disabled) on all other platforms, which is confusing and
inefficient. Better use real dependencies so that the symbols do not
exist at all on platforms where they are not relevant.
