Allow device trees to be reused between Linux and U-Boot.
The source for these device trees is linux-next as of commit
bd8a9cd624c6 ("arm64: dts: ls1028a-rdb: update copyright"), which was
chosen because some changes needed to be done to the Linux DTs too,
before they could be shared:
https://lore.kernel.org/linux-arm-kernel/20211202141528.2450169-5-vladimir.oltean@nxp.com/T/#m6f63c92e75fa79a01144b2c2c6dc4776e7971395
There are two more commits on the RDB device tree which haven't been
picked up yet, because they have dependencies on the SoC device tree:
dd3d936a1b17 ("arm64: dts: ls1028a: add ftm_alarm1 node to be used as wakeup source")
b2e2d3e02fb6 ("arm64: dts: ls1028a-rdb: enable pwm0")
These will be picked up on the next resync.

Reuse the scheme implemented by the Kontron SL28 boards in
commit d08011d7f9
("arm: dts: ls1028a: disable the PCIe controller by default")
and move the 'status = "okay"' lines for the PCIe controllers
inside a separate U-Boot dtsi for the LS1028A-RDB board. This way, the
existing Linux device tree can simply be dropped in.

There is no SPI peripheral on the LS1028A-RDB, therefore no reason to
enable these nodes in the U-Boot device tree (and Linux does not enable
them either).

In a bit of a blunder, the blamed commit in the Fixes: tag below made
the mscc_felix switch driver look at the 'managed = "in-band-status"'
device tree property, forgetting that the U-Boot device tree had not
been updated to include that property, whereas the Linux one does.
The switch is therefore described in the device tree as not requiring
in-band autoneg, but the PHY driver for VSC8514 (drivers/net/phy/mscc.c)
still enables that feature. This results in a mismatch => no traffic.
This patch is a copy-paste of the Ethernet device tree nodes from Linux,
which resolves that issue. The device tree update also renames the
Ethernet PHY labels.

During this board's sync with Linux device trees, it was observed that
it doesn't use the same compatible string for the RTC node as in U-Boot.
This change makes the RTC compatible strings match, for a smoother sync.

Disable the PCIe controllers by default, just like in the linux device
tree. But there is one catch, for linux they are enabled in-place by the
bootloader. Obviously, this doesn't work for the bootloader. Thus we
explicitly enable the controllers in the -u-boot.dtsi files.

Linux uses the prefix "ethernet" whereas u-boot uses "eth". This is from
the linux tree:
$ grep "eth[0-9].*=.*&" arch/**/*dts{,i}|wc -l
0
$ grep "ethernet[0-9].*=.*&" arch/**/*dts{,i}|wc -l
633
In u-boot device trees both prefixes are used. Until recently the only
user of the ethernet alias was the sandbox test device tree. This
changed with commit fc054d563b ("net: Introduce DSA class for Ethernet
switches"). There, the MAC addresses are inherited based on the devices
sequence IDs which is in turn given by the device tree.
Before there are more users in u-boot and both worlds will differ even
more, rename the alias prefix to "ethernet" to match the linux ones.
Also adapt the test cases and rename any old aliases in the u-boot
device trees.

The definition follows the DSA binding in kernel and describes the switch,
its ports and PHYs. The switch node has the same structure as in Linux
and this patch enables it (and relevant ports) for the LS1028A RDB board.
ENETC PF6 is the 2nd Eth controller linked to the switch on LS1028A, it is
not used in U-Boot and was disabled. Ethernet port aliases were also
added to better manage the multitude of ports available now.
