arm64: dts: ls1028a-rdb: add more ethernet aliases

Commit "arm64: dts: ls1028a: enable swp5 and eno3 for all boards" which
Shawn declared as applied, but for which I can't find a sha1sum, has
enabled a new Ethernet port on the LS1028A-RDB (&enetc_port3), but
U-Boot, which passes a MAC address to Linux' device tree through the
/aliases node, fails to do this for this newly enabled port.

Fix that by adding more ethernet aliases in the only
backwards-compatible way possible: at the end of the current list.

And since it is possible to very easily convert either swp4 or swp5 to
DSA user ports now (which have a MAC address of their own), using these
U-Boot commands:

=> fdt addr $fdt_addr_r
=> fdt rm /soc/pcie@1f0000000/ethernet-switch@0,5/ports/port@4 ethernet

it would be good if those DSA user ports (swp4, swp5) gained a valid MAC
address from U-Boot as well. In order for that to work properly,
provision two more ethernet aliases for &mscc_felix_port{4,5} as well.

The resulting ordering is slightly unusual, but to me looks more natural
than eno0, eno2, swp0, swp1, swp2, swp3, eno3, swp4, swp5.
