As exposed by "make randconfig", we have an issue with the dependencies
for PINCTRL_TH1520. It really needs to depend on PINCTRL_GENERIC rather
than select it, and PINCTRL_GENERIC in turn already depends on
PINCTRL_FULL.

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.

This driver adds the base support of pinctrl over SCMI.  The driver
does two main things.  First, it allows you to configure the initial
pin states.  Secondly, it's used a base to build a GPIO driver on
top of it.

To configure the states then add a pinmux config to the scmi_pinctrl
section:

        scmi_pinctrl: protocol@19 {
                reg = <0x19>;
                pinmux1: pinmux_test {
                        pinmux = <0 1 0xFFFFFFFF 18 1
                                  0 2 0xFFFFFFFF 18 1
                                  0 3 0xFFFFFFFF 18 1>;
                        function = "f_gpio1";
                        groups = "grp_1", "grp_3";
                };
        };

Under linux the pinctrl subsystem will parse the function and group
properties and use that to handle muxing.  However, under u-boot the
pin muxing is done using the "pinmux" property, which feeds raw SCMI
pinctrl PINCTRL_SETTINGS_CONFIGURE commands to the server.  The
numbers are: selector, identifier, function_id, config_type, and
config_value.  In the example above, it sets pins 1, 2, and 3 to 1.
The linux-kernel ignores this pinmux property.

Add all the pinctrl message IDs.  I renamed SCMI_MSG_PINCTRL_CONFIG_SET
to SCMI_PINCTRL_SETTINGS_CONFIGURE so the naming matches the spec better.

Multiple pads can drive the same module input pin, and a daisy chain
register is used to select the active input path. This patch defines
DAISY_OFFSET_IMX952 (0x460) and allows binding on i.MX952.

A fix:
* Fixing compiling MT8195 due to some independent changes that were applied
  around the same time as MT8195 support was merged. (CI would not have caught
  this since we didn't have a defconfig until now).

And few small features:
* New defconfig for MT8395/Genio 1200 EVK.
* pinctrl support for MT8189-compatible SoCs.

Add pinctrl support for mt8189.

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.
