mediatek: backport new pinctrl features
Backport new features for MediaTek pinctrl/pinconf drivers from upstream.
This will serve as the base to improve pinconf bias/pull-up/pull-down on
MT7981 and MT7986, and also prepare for upcoming support for MT7988.

+
+This patch supports rsel(resistance selection) feature for I2C pins.
+It provides more resistance selection solution in different ICs.
+It provides rsel define and si unit solution by identifying
+"mediatek,rsel_resistance_in_si_unit" property in pio dtsi node.

+Subject: [PATCH] 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.

+Commit fb34a9ae383a ("pinctrl: mediatek: support rsel feature")
+introduced SoC specify 'pull_type' attribute to mtk_pinconf_bias_set_combo
+and mtk_pinconf_bias_get_combo, and make the functions able to support
+almost all Mediatek SoCs that use pinctrl-mtk-common-v2.c.
+
+This patch enables pinctrl_moore to support these functions.
