Subject: [PATCH] arm64: dts: fsl: ls1028a: Specify that the Felix port 4 runs
 at 2.5Gbps

This is just an informative change, because all Felix MACs inside the
LS1028A are hardwired in gigabit mode anyway.

Only PHYLINK is able to understand fixed-link speeds higher than 1 Gbps.
With PHYLIB, fixed-link interfaces are emulated as C22 PHYs by the swphy
driver, and C22 does not specify settings for speeds higher than
gigabit.

This patch brings no functional change except for the messages printed
during driver initialization.
