[PATCH net v5 0/3] net: stmmac: re-apply taprio offload in __stmmac_open() and stmmac_resume()

Reconfigure MTL_EST registers after sw reset in __stmmac_open().
Remove priv->est->enable dependency in est_configure().
Initialize est_lock at probe time.

Changes in v5:
- Reconfigure preemption_class in stmmac_setup_est().
- Bail out in stmmac_setup_est() if ptp is not enabled.
- Link to v4: https://lore.kernel.org/r/20261026-stmmac-est-fixes-v4-0-999dac4de44f@oss.qualcomm.com (local)

Changes in v4:
- Rebase on top of net main branch

Changes in v3:
- Guard priv->est.enable update using est_lock mutex.
- Embed stmmac_est in stmmac_priv struct.
- Rework locking in tc_taprio_configure().
- Fix possible divided by zero crash in tc_taprio_configure().
- Add missing reconfiguration during stmmac_resume().
- Honor ptp error code in __stmmac_open() and stmmac_resume().
- Link to v2: https://lore.kernel.org/r/20260829-stmmac-est-reapply-after-open-v2-1-5e5ccb185e92@oss.qualcomm.com (local)

Changes in v2:
- Rename stmmac_est_reconfigure() in stmmac_setup_est().
- Rely on stmmac_setup_est() in tc_taprio_configure().
- Link to v1: https://lore.kernel.org/r/20260825-stmmac-est-reapply-after-open-v1-1-dfa80735e0a1@oss.qualcomm.com (local)
