powerpc: drop MPC85xx_CDS platform support
The MPC8541/8548/8555 Configurable Development System (CDS) were the
vehicle used to provide evaluation of the 1st e500-v2 CPUs around 2007.
Similar to the earlier MPC83xx-MDS systems we removed, the "brains"
exist on a PCI-X card, but additional connectors exist to the right of
the PCI-X slot, two structural metal pins are used to provide stability
in a vertical ATX mounting, and the CPU is now on a daughter-card vs. a
clamped down BGA.
Given the extra complexity and risk of connector damage, the 8548CDS
I had access to came pre-assembled in a basic white Antec case common
for that era, and I'm inclined to assume that was the default.
Power was typical "Pentium4" 2005 ATX - the main 20 pin connector went
to the PCI ATX form factor backplane, and the 4 pin black/yellow went
to the CPU card.
Like previous evaluation boards, they attempted to provide break-out
connectors for as many features as possible, and that made for a fairly
complex looking system.
In any case, these are over 15 years old, and fairly complex systems,
originally made for a small group of industry related people, and made
for use where quiet fan operation wasn't important. Given that, it
makes sense to remove support from them in 2023.

powerpc: dts: t1040rdb: enable both CPU ports
Since commit eca70102cfb1 ("net: dsa: felix: add support for changing
DSA master") included in kernel v6.1, the driver supports 2 CPU ports,
and they can be put in a LAG, for example (see
Documentation/networking/dsa/configuration.rst for more details).
Defining the second CPU port in the device tree should not cause any
compatibility issue, because the default CPU port was &seville_port8
before this change, and still is &seville_port8 now (the numerically
first CPU port is used by default).

powerpc: dts: t1040rdb: fix ports names for Seville Ethernet switch
On board rev A, the network interface labels for the switch ports
written on the front panel are different than on rev B and later.
This patch fixes network interface names for the switch ports according
to labels that are written on the front panel of the board rev B.
They start from ETH3 and end at ETH10.
This patch also introduces a separate device tree for rev A.
The main device tree is supposed to cover rev B and later.

powerpc: dts: t1040rdb: add ports for Seville Ethernet switch
Define the network interface names for the switch ports and hook them up
to the 2 QSGMII PHYs that are onboard.
A conscious decision was taken to go along with the numbers that are
written on the front panel of the board and not with the hardware
numbers of the switch chip ports.
