Subject: [PATCH] arm64: dts: fsl: ls1028a: Add Felix switch port DT node

Add the switch device node, available on PF5, so that the
switch port sub-nodes (net devices) can be linked to
corresponding board specific phy nodes (external ports) or
have their link mode defined (internal ports).
The switch device features 6 ports, 4 with external links
and 2 internally facing to the ls1028a SoC and connected via
fixed links to 2 internal enetc ethernet contoller ports.
Add the corresponding enetc internal port device nodes,
mapped to PF2 and PF6 PCIe functions.
And don't forget to enable the 4MB BAR4 in the root complex
ECAM space, where the switch registers are mapped.
