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).
