Commit f4df9f53b7a9 ("pinctrl: mediatek: Bind gpio while binding pinctrl")
refactored pinctrl-mtk-common.c and the SoC-specific drivers to register
the gpiochip during the bind phase instead of probe. As part of this
change, each SoC driver must implement a bind callback.

The drivers recently added for mt8188, mt8189, mt8195 and mt8365 do not
define this callback, which prevents the gpiochip from being registered
properly.

Add the missing bind callback to these drivers.

Increase the maximum number of base addresses that can be handled by the
mediatek pinctrl driver from 10 to 15. This is needed for the MT8189
which has 15 base addresses.

Add a bounds check on the number of base addresses to prevent
out-of-bounds access to the priv->base array.

Replace uclass_get_device_by_ofnode() with syscon_regmap_lookup_by_phandle()
to get the "mediatek,pctl-regmap" syscon device.

Depending on probe order, uclass_get_device_by_ofnode() may fail, but
syscon_regmap_lookup_by_phandle() has logic in it to handle that case
correctly.

The previous implementation could read more than one syscon if the
"mediatek,pctl-regmap" property had more than one phandle, but the one
board with a devicetree that does that is not supported in U-Boot yet,
so we can save that for later (it may never be needed).
