  This patch series enhances debug logs for pm80xx HW events, and provides
a minor fix in the case of a hard reset. The log enhancement involves
changing the log severity level to enable logging for HW events
which consequently help debug disk discovery issues.

1. Changed log severity level from MSG to EVENT for HW events.
Enhanced the HW event logs by adding the phyid.

2. Enabled INIT logging.

3. Log portid along with the PHY_UP event.

4. Print phyid and portid sent as part of device registration
request.

5. Log port state during HW events.

6. Update phy_state and phy_attached to correct values after
a hard reset.
