4cd5ce5a7f ramips: increase SPI frequency for MT7620 Archer
Increase the SPI frequency for the MT7620 based TP-Link Archer
series to 30MHz.

TP-Link uses different SPI flash chips for the same board
revision, so be conservative to not break boards with a
different chip. 30MHz should be well supported by all chips.

Tested on Archer C2 v1 (GD25Q64B) and Archer C20i (W25Q64FV).

Archer C20i (before)
====================
root@OpenWrt:~# time dd if=/dev/mtd1 of=/tmp/test.bin bs=64k
122+0 records in
122+0 records out
real	0m 15.30s
user	0m 0.00s
sys	0m 15.29s

Archer C20i (after)
===================
root@OpenWrt:~# time dd if=/dev/mtd1 of=/tmp/test.bin bs=64k
122+0 records in
122+0 records out
real	0m 5.99s
user	0m 0.00s
sys	0m 5.98s

d7a28e8ed2 ramips: mt7620: tidy up ethernet node in DTS files
This tidies up the ethernet node in mt7620 DTS files by:

- removing unnecessary status as it is not disabled
- reordering properties consistently
- adding empty lines to enhance readability

This should make comparison and reviewing new PRs based on C/P easier.

1eceab3fc0 ramips: dts: use generic node name for flash
In DTS Checklist[1] we're now demanding proper generic node names, as
the name of a node should reflect the function of the device and use
generic name for that[2]. Everybody seems to be copy&pasting from DTS
files available in the repository today, so let's unify that naming
there as well and provide proper examples.

While at it, remove unused m25p80 label.

Tested on rt5350 (for spi-nor) and rt3662 (for cfi-flash).

757658f2ab ramips: create common DTSI for TP-Link Archer C20i/C20 v1/C50 v1
The TP-Link Archer C20i/C20 v1/C50 v1 seem to be almost the same,
so creating a common DTSI will reduce duplicate code.
