[RESEND 1/3] ASoC: ics43432: add CMM-4030D-261 support

[Angelo Dureghello]

Despite minimal datasheet differences, the driver seems
perfectly compatible with CMM-4030D-261.

Tested CMM-4030D-261 to work with this changes:

/ {
        cmm4030d: cmm4030d {
                #sound-dai-cells = <0>;
                compatible = "cui,cmm-4030d-261";
        };

        sound_mic {
                compatible = "simple-audio-card";
                simple-audio-card,name = "i2s mem mic";
                simple-audio-card,format = "i2s";
                simple-audio-card,bitclock-master = <&sound_master>;
                simple-audio-card,frame-master = <&sound_master>;
                sound_master: simple-audio-card,cpu {
                        sound-dai = <&ssi2>;
                        system-clock-frequency = <2822400>;
                };
                simple-audio-card,codec {
                        sound-dai = <&cmm4030d>;
                };
        };
};

Audio has been captured and tested successfully by:

arecord -D "hw:1,0" -f S24_LE > test.wav
aplay test.wav

This is an unrelated change not identified in the changelog, it should
have been submitted as a separate patch.

cui isn't a know vendor prefix, you should also update the list of
vendors in vendor-prefixes.yaml.

Ah, this patch should've been before the patch adding the use.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
