Revert "HID: playstation: add microphone mute support for DualSense."

This reverts commit d5f7af85a537 ("HID: playstation: add microphone
mute support for DualSense.")

There is currently an ongoing discussion on linux-leds LKML,
and so to give us more room, we need to revert those related
patches from linux-next.

This is not a big deal, they are still not pushed to Linus.
