Since the nvmem-based approach for retrieving MAC addresses
appears to depend on the addresses being set up after the
partitions, it is no longer possible to keep the MAC address
setup in shared DTSI files while the partitions itself are
set up in DTS files for the individual devices.
In ath79 the firmware partition is typically located somewhere
"in the middle" of the partition table. Thus, it's not trivial
to share the partitions containing MAC address information in
a common DTSI (like we did in some cases on ramips).
In this commit, MAC address setup is thus moved to the relevant
partitions, and in most cases needs to be duplicated. While
the duplication is not really nice, it eventually provides a
cleaner and more tidy setup, making the DTS(I) file
fragmentation a bit more logical. This should also help
with adding new devices, as information is distributed across
less locations.
For consistency, this commit also moves the mtd-cal-data property
"down" together with the MAC address setup, so it's not based
on a partition before the latter is defined either. (This is
only done for those files touched due to nvmem conversion.)

Convert most of the cases from mtd-mac-address to nvmem where
MAC addresses are set in the DTSI, but the partitions are only
located in the device DTS. This posed some problems earlier, since
in these cases we are using partitions before they are defined,
and the nvmem system did not seem to like that.
There have been a few different resolution approaches, based on
the different tradeoffs of deduplication vs. maintainability:
1. In many cases, the partition tables were identical except for
the firmware partition size, and the firmware partition was
the last in the table.
In these cases, the partition table has been moved to the
DTSI, and only the firmware partition's "reg" property has
been kept in the DTS files. So, the updated nvmem definition
could stay in the DTSI files as well.
2. For all other cases, splitting up the partition table would
have introduced additional complexity. Thus, the nodes to be
converted to nvmem have been moved to the DTS files where the
partitioning was defined.
3. For Netgear EX2700 and WN3000RP v3, the remaining DTSI file
was completely dissolved, as it was quite small and the name
was not really nice either.
4. The D-Link DIR-853 A3 was converted to nvmem as well, though
it is just a plain DTS file not taken care of in the first
wave.
In addition, some minor rearrangements have been made for tidyness.
Not covered (yet) by this patch are:
* Various unielec devices
* The D-Link DIR-8xx family

The mt76x8 subtarget is the only one in ramips that stores the
mediatek,mtd-eeprom property directly in the "root" mt7628an.dtsi.
This is not optimal for a few different reasons:
* If you don't really know it or are used to other (sub)targets,
the property will be set somewhat magically.
* The property is set based on &factory partition before (if at all)
this partition is defined.
* There are several devices that have different offset or even
different partitions to read from, which will then be overwritten
in the DTS files. Thus, definitions are scattered between root
DTSI and individual files.
Based on these circumstances, the "root" definition is removed and
the property is added to the device-based DTS(I) files where needed
and applicable. This should be easier to grasp for unexperienced
developers and will move the property closer to the partition
definitions.

When a target configuration has unser Kconfig symbols, the build will
fail when OpenWrt is compiled with V=s and stdin is connected to a tty.
In case OpenWrt is compiled without either of these preconditions, the
build will uscceed with the symbols in question being unset.
Modify the kernel configuration in a way it fails on unset symbols
regardless of the aformentioned preconditions.

Calling free for the OF property can result in a kernel panic, as the
buffer in question might be referenced elsewhere. Also, it is not
removed from the tree.
Always allocate a new property and updating the tree with it fixes both
issues.

It waits to be accepted upstream, however, it waits for Marvell people to respond.

Based on the discussion on the mailing list [1], the patch which was
reverted, it reverts only one patch without the subsequent ones.
This leads to the SoC scaling issue not using a CPU parent clock, but
it uses DDR clock. This is done for all variants, and it's wrong because
commits (hacks) that were using the DDR clock are no longer in the mainline kernel.
If someone has stability issues on 1.2 GHz, it should not affect all
routers (1 GHz, 800 MHz) and it should be rather consulted with guys, who are trying to
improve the situation in the kernel and not making the situation worse.
There are two solutions in cases of instability:
a) disable cpufreq
b) underclock it up to 1 GHz
This reverts commit 080a0b74e3.

"In case SFP module is present, U-Boot has to enable the sfp node above,
remove phy-handle property, and add managed = "in-band-status" property."
