mt76: connac: introduce MCU_CE_CMD macro

commit 680a2ead741ad9b479a53adf154ed5eee74d2b9a upstream.

Similar to MCU_EXT_CMD, introduce MCU_CE_CMD for CE commands

Stable kernel notes:

Upstream commit 547224024579 (mt76: connac: introduce MCU_UNI_CMD macro,
2021-12-09) introduced a bug by removing MCU_UNI_PREFIX, but not
updating MCU_CMD_MASK accordingly, so when commands are compared in
mt7921_mcu_parse_response() one has the extra bit __MCU_CMD_FIELD_UNI
set and the comparison fails:

  if (mcu_cmd != event->cid)
  if (20001 != 1)

The fix was sneaked by in the next commit 680a2ead741a (mt76: connac:
introduce MCU_CE_CMD macro, 2021-12-09):

-       int mcu_cmd = cmd & MCU_CMD_MASK;
+       int mcu_cmd = FIELD_GET(__MCU_CMD_FIELD_ID, cmd);

But it was never merged into linux-stable.

We need either both commits, or none.
