sc7180: Increase SPI flash frequency to 37.5MHz

It seems that all SC7180 boards we have can well handle 37.5MHz of SPI
flash speed, so bump that up from the current 25MHz so that we don't
leave boot speed on the table. (The next step would be 50MHz which
currently doesn't work on all boards so we're not going there yet.)
