74516f4357 ramips: fix reboot for remaining 32 MB boards
The following devices have a Winbond W25Q256FV flash chip,
which does not have the RESET pin enabled by default,
and otherwise would require setting a bit in a status register.

Before moving to Linux 5.4, we had the patch:
0053-mtd-spi-nor-add-w25q256-3b-mode-switch.patch
which kept specific flash chips with explicit 3-byte and 4-byte address modes
to stay in 3-byte address mode while idle (after an erase or write)
by using a custom flag SPI_NOR_4B_READ_OP that was part of the patch.

this was obsoleted by the patch:
481-mtd-spi-nor-rework-broken-flash-reset-support.patch
which uses the newer upstream flag SNOR_F_BROKEN_RESET
for devices with a flash chip that cannot be hardware reset with RESET pin
and therefore must be left in 3-byte address mode when idle.

The new patch requires that the DTS of affected devices
have the property "broken-flash-reset", which was not yet added for most of them.

This commit adds the property for remaining affected devices in ramips target,
specifically because of the flash chip model.

However, it is possible that there are other devices
where the flash chip uses an explicit 4-byte address mode
and the RESET pin is not connected to the SOC on the board,
and those DTS would also need this property.

ad6b077049 ramips: mt7628: move mtd-eeprom out of root DTSI
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.

b69c21738e treewide: add space before SPDX identifier
Strictly, an SPDX identifier requires a space between the comment
marker and the identifier itself. The choice of the comment marker
itself is irrelevant.

Correct:

// SPDX-License-Identifier: GPL-2.0-or-later OR MIT

Wrong:

//SPDX-License-Identifier: GPL-2.0-or-later OR MIT

Fix that in the whole tree (actually, only ramips contained wrong
uses).

c846dd91f0 ramips: remove model name from LED labels
Like in the previous patch for ath79 target, this will remove the
"devicename" from LED labels in ramips as well.

The devicename is removed in DTS files and 01_leds, consolidation
of definitions into DTSI files is done where (easily) possible,
and migration scripts are updated.

For the latter, all existing definitions were actually just
devicename migrations anyway. Therefore, those are removed and
a common migration file is created in target base-files. This is
actually another example of how the devicename removal makes things
easier.

621297e867 ramips: move dts-v1 statement to top-level DTSI files
The "/dts-v1/;" identifier is supposed to be present once at the
top of a device tree file after the includes have been processed.

In ramips, we therefore requested to have in the DTS files so far,
and omit it in the DTSI files. However, essentially the syntax of
the parent mtxxxx/rtxxxx DTSI files already determines the DTS
version, so putting it into the DTS files is just a useless repetition.

Consequently, this patch puts the dts-v1 statement into the top-level
SoC-based DTSI files, and removes all other occurences.
Since the dts-v1 statement needs to be before any other definitions,
this also moves the includes accordingly where necessary.

a66449c608 ramips: drop remaining m25p,chunked-io from DTS
This option was a spi nor hack which is dropped in commit bcf4a5f474
("ramips: remove chunked-io patch and set spi->max_transfer_size instead")

Most of it has already been removed in
be2b61e4f1 ("ramips: drop m25p,chunked-io from dts")

It seems all current usages were added after that. Remove them.

633ea0db0f ramips: WizFi630S use macs from factory partion
WIZnet WizFi630s has three mac addresses in the factory partition:
0x04 (also on the label), 0x28 for wan mac and 0x2e as lan mac.
All three macadresses are sequential series of addresses.
This is making use of them.

While at it, also add the label MAC address to 02_network.

MAC addresses as verified by OEM firmware:

use      interface   source
WLAN     ra0         factory 0x04 (label)
WAN      eth0.2      factory 0x28 (label + 1)
LAN      eth0.1      factory 0x2e (label + 2)

d0b229f553 ramips: correct WizFi630S pin mappings
WizFi630S had some pins changed in the release version of the board.
The run led, wps button and a slide switch where affected.
This patch is correcting this.
i2c is removed as it is sharing a pin with the run (system) led.
uart2 is enabled as it is also enabled in the OEM firmware.
