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)
====================

Archer C20i (after)
===================
