SRU Justification:
======================
[Impact]
Keyboard is lost after updated to 6.5.0-27 and oem-6.5-1019 kernel
versions.

[Fix]
Regression commit is found commit:
936e4d49ecbc ("Input: atkbd - skip ATKBD_CMD_GETID in translated mode")

Fixes:
9cf6e24c9fbf1 Input: atkbd - do not skip atkbd_deactivate() when
skipping ATKBD_CMD_GETID
683cd8259a9b8 Input: atkbd - skip ATKBD_CMD_SETLEDS when skipping
ATKBD_CMD_GETID

[Test]
Tested on hardware, keyboard works fine after bootup.

The regression commit is only in 6.5 stable, so SRU for 6.5 only.

[Where problems could occur]
It may break keyboard.
