For AM65x SR2.0 it's required to enable IEP1 in raw 64bit mode which is used by PRU FW to monitor the link and apply w/a for 10M link issue. Note. No public errata available yet. Without this w/a the PRU FW will stuck if link state changes under TX traffic pressure. Hence, add support for 10M full duplex for AM65x SR2.0: - add new IEP API to enable IEP, but without PTP support - add pdata quirk_10m_link_issue to enable 10M link issue w/a.
