[PATCH v2 0/3] drm/msm/dp, phy: qcom: improve DP Type-C reconnect handli

[naidu nama <naidu.nama@oss.qualcomm.com>]

This series improves the Qualcomm DP Type-C bring-up and reconnect paths
by handling PHY initialization races and link-training corner cases more
consistently.

The fixes cover races and link-training corner cases in the Qualcomm DP
Type-C path. They prevent Type-C mux switching while the DP PHY is still
initializing, avoid unnecessary retraining after a successful link train,
and keep the downgrade retry path running across transient AUX disconnects 
when the cable is still plugged.

Together these changes make DP reconnect and orientation-switch
handling more robust.

[v2]

- Updated the commit message [Konrad, Dmitry]
- Handled the force_link_train varibale usage [Konrad]
- Handled the plugged field from struct msm_dp_ctrl,
  by passing  the current dp->plugged value as a function argument [Dmitry]
- Dropped the drm/msm/dp: skip LTTPR init when no LTTPRs are present[Konrad, Dmitry]
