Summary of Changes

Add fixes to drivers/net/ethernet to support NVIDIA Orin

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2122405

Add support for the Multi-Gigabit Ethernet (MGBE/XPCS) IP found on NVIDIA Tegra234 SoCs.

The Tegra MGBE ethernet controller requires that the SERDES link is powered-up after the PHY link is up, otherwise the link fails to become ready following a resume from suspend. Add a variable to indicate that the SERDES link must be powered-up after the PHY link.

Fix DMA engine reset timeout issue in suspend/resume with ADLink I-Pi SMARC Plus board
