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).

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.

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