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.

According to https://docs.onion.io/omega2-docs/mac-address.html, 0x28 is
the correct location to read the address on Onion Omega 2(+) devices.
This fixes a regression introduced by commit 77e850fe76 ("ramips: tidy up
MAC address setup for Linkit Smart and Omega2"), which was a cleanup that
intended to preserve existing behavior. In my testing with v19.07.7,
however, the MAC address determined from the device tree takes precedence
over the one set by 02_network, so the aforementioned commit actually
changed the behavior.

[Adapt patch to nvmem usage]
Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
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.

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.

Linkit Smart 7688 and Onion Omega 2(+) are one-port devices, and
have their port set to LAN by default. Setting up a WAN MAC address
for them doesn't make any sense, as no wan interface will be created
in uci config. Despite, these devices also set lan_mac in 02_network,
although mtd-mac-address sets a different address for the ethernet
interface in DTS.
Clean this up by moving the lan_mac value into DTS and dropping the
entries in 02_network completely. That way, the effective address
on the LAN interface should stay the same, but we get rid of the
extra (re)assignments.
As I don't have access to the devices, this does not tell anything
about whether 0x2e is actually a good choice, it just preserves
the existing assignment.

Upstream pinctrl driver in drivers/staging uses

The node pinctrl0 is already set up in the SOC DTSI files, but
defined again as member of pinctrl in most of the device DTS(I)
files. This patch removes this redundancy for the entire ramips
