Shiji Yang c36e47c5da ramips: increase SPI frequency for Phicomm series devices
From many teardown image in the internet, I find Phicomm K1/k2 series use
Winbond W25Q64/W25Q128 or GigaDevice GD25Q64/GD25Q128 Flash chips. both of
them support 100+ MHz clock spi operate and fast-read instruction. PSG1218
with W25x or GD25x has been tested and it can run well in OpenWrt v19.07.
