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.

Since the CPU port 4 of the switch is hardwired inside the SoC to go to

to set (but whether that CPU port is used or not is another discussion).

It turns out that it is not necessary to declare the VSELECT signal as
GPIO and let the PMIC driver set it to a fixed high level. This switches
the voltage between 3.3V and 1.8V by setting the PMIC register for LDO5
accordingly.
Instead we can do it like other boards already do and simply mux the
VSELECT signal of the USDHC interface to the pin. This makes sure that
the correct voltage is selected by setting the PMIC's SD_VSEL input
to high or low accordingly.
