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.

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.

Upstream pinctrl driver in drivers/staging uses
groups/function/ralink,num-gpios instead of
ralink,group/ralink,function/ralink,nr-gpio
Replace these properties in dts as well as the pinctrl driver in
patches-4.14.

Several devices in mt76x8 subtarget use the following line to set
up wmac in their DTS(I) files:
ralink,mtd-eeprom = <&factory 0x4>
This is strange for several reasons:
- They should use mediatek,mtd-eeprom on this SOC
- The caldata is supposed to start at 0x0
- The parent DTSI mt7628an.dtsi specifies mediatek,mtd-eeprom anyway,
starting from 0x0
- The offset coincides with the default location of the MAC address
in caldata
Based on the comment in b28e94d4bf ("ramips: MiWiFi Nano fixes"),
it looks like the author for this device wanted to actually use
mtd-mac-address instead of ralink,mtd-eeprom. A check on the same
device revealed that actually the MAC address start at offset 4 there,
so the correct caldata offset is 0x0.
Based on these findings, and the fact that the expected location on
this SOC is 0x0, we remove the "ralink,mtd-eeprom = <&factory 0x4>"
statement from all devices in ramips (being only mt7628an anyway).
Thanks to Sungbo Eo for finding and researching this.

This patch does the following things:
1. mark u-boot-env writable
2. add bootcount support
Currently, u-boot has a flag_boot_success env variable to reset.
Also reset it in our firmware to follow the behavior in vendor's
firmware.
3. disable usb support
This router doesn't have usb port at all.
4. increase spi clock to 40MHz
5. fix pinmux groups
