acpigen_ps2_keybd: Support a Do Not Disturb key

This commit simply adds support for a Do Not Disturb key. HUTRR94 added
support for a new usage titled "System Do Not Disturb" which toggles a
system-wide Do Not Disturb setting.

BUG=b:342467600
TEST=Build and flash a board that generates a scancode for a Do Not
Disturb key. Verify that KEY_DO_NOT_DISTURB is generated in the Linux
kernel with patches[0] that add this new event code using `evtest`.
