142173c4ad pinctrl: mediatek: Switch to use no-IRQ PM helpers
Since pm.h provides a helper for system no-IRQ PM callbacks,
switch the driver to use it instead of open coded variant.

5754a1c98b pinctrl: mediatek: Fix the drive register definition of some Pins
The drive adjustment register definition of gpio13 and gpio81 is wrong:
"the start address for the range" of gpio18 is corrected to 0x000,
"the start bit for the first register within the range" of gpio81 is
corrected to 24.

e1ff91f9d2 pinctrl: mediatek: Fix EINT pins input debounce time configuration
The External Interrupt Controller (EINTC) on all of the supported
MediaTek SoCs does support input debouncing, but not all of them
index the debounce time values (DBNC_SETTING registers) the same way.

Before this change, in some cases, as an example, requesting a debounce
time of 16 milliseconds would mistakenly set the relative DBNC_SETTING
register to 0x2, resulting in a way shorter debounce time of 500uS.

To fix the aforementioned issue, define three different debounce_time
arrays, reflecting the correct register index for each value and for
each register index variant, and make sure that each SoC pinctrl
driver uses the right one.

78df7bba4a pinctrl: mediatek: paris: Unify probe function by using OF match data
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.

Setting this up will configure wake from suspend properly,
and wake only for the interrupts that are setup in wake_mask,
not all interrupts.
