[PATCH AUTOSEL 6.7 01/14] arm64: tegra: Set the correct PHY mode for MGBE

[Sasha Levin]

From: Thierry Reding <treding@nvidia.com>

[ Upstream commit 4c892121d43bc2b45896ca207b54f39a8fa6b852 ]

The PHY is configured in 10GBASE-R, so make sure to reflect that in DT.

From: Johan Hovold <johan+linaro@kernel.org>

[ Upstream commit db8138845cebcdd0c709570b8217bd052757b8df ]

Limit the WiFi PCIe link speed to Gen2 speed (500 MB/s), which is the
speed that Windows uses.
