[PATCH 0/1][SRU][L/K/J] Fix speaker mute hotkey doesn't work on Dell G16 series

[Koba Ko]

BugLink: https://bugs.launchpad.net/bugs/2003161

[Impact]
Speaker mute and Mic mute hotkey no function on the G16.

[Fix]
speaker mute event is sent by EC then dell-wmi can't recognize it.

Add a new keymap for KEY_MUTE.

Send for OEM kernels first then will SRU for generic kernel once the patch is merged.

[Test Case]
1. boot-up with the kernel applied the fix.
2. Play video/audio.
3. Press the speak-mute hotkey
4. can't hear any sounds.

[Where problems could occur]
Low, only add a keymap the affect would be very limited.
