David Bauer 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

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