mediatek: filogic: increase spi flash memory speed on ZyXEL EX5601
Reduces boot time by 3s on a freshly installed image. This device
has a large flash and the gain can be higher with more packages
installed. According to the datasheet, this is the maximum frequency
supported by the Micron and Macronix chips that are installed in
these devices. Tested on three units over a two month period.
