[PATCH] crypto: caam/qi2 - reset the DPSECI at probe only when enabled

[Vincent Jardin via B4 Relay]

From: Vincent Jardin <vjardin@xxxxxxx>

Since the commit
  060ce5037d5f ("crypto: caam/qi2 - add support for dpseci_reset()")
probe resets every DPSECI.

On a DPSECI the MC has just created from the DPL, never enabled,
MC 10.40.x then logs for each of its queues:

  [E, qbman_rec_isr:396, QBMAN]  QBMAN recoverable event 0x1000000
  [E, dpmng_dump_rerr_fqid:1335, QBMAN]  REL_FQ (FQ[0]) has 1 messages, dumping up to 16:
  [W, DPSECI]  DPSECI ID[0]: Flush on queue 43 not confirmed

That is 16 error lines for an 8-queue DPSECI, at every boot, although
there is nothing to flush: a disabled DPSECI has no request in flight.

The reset at remove is unchanged.
