All of the SoCs using Paris pinctrl are defining a custom probe
function that is simply calling mtk_paris_pinctrl_probe() passing
a pointer to the SoC specific mtk_pin_soc structure and nothing else.
Simplify the probe mechanism across all pinctrl drivers that are
using pinctrl-paris by passing the specific mtk_pin_soc as match
data and using function mtk_paris_pinctrl_probe as a common probe
function for all of them.

Add support for pin configuration dump via catting
/sys/kernel/debug/pinctrl/$platform_dependent_path/pinconf-pins.
pinctrl framework had already support such dump. This patch implement the
operation function pointer to fullfill this dump.

pinctrl variants that include pinctrl-paris.h (and not
pinctrl-mtk-common.h) also need to use pm_ops to setup
wake mask properly, so copy over the pm_ops from common
to paris variant.
It is not easy to merge the 2 copies (or move
mtk_eint_suspend/resume to mtk-eint.c), as we need to
dereference pctrl->eint, and struct mtk_pinctrl *pctl has a
different structure definition for v1 and v2 (which is
what paris variant uses).

Include only <linux/gpio/driver.h> since this is a driver,
not a consumer.

Add pinctrl-paris core that implements vendor dt-binding which MediaTek
tablet, box and smartphone-based SoCs such as MT81xx, MT27xx, and MT67xx
SoCs really want to depend on. The driver is just completely rewritten
according to pinctrl-mtk-common.c but uses the new logic from
pinctrl-mtk-common-v2.c to have an elegant way to support new SoCs in the
future.
