spi/rockchip: Avoid accidentally turning off the clock If our client is requesting a clock that is above the maximum clock then the following division will result in 0: rs->max_freq / rs->speed We'll then program 0 into the SPI_BAUDR register. The Rockchip TRM says: "If the value is 0, the serial output clock (sclk_out) is disabled." It's much better to end up with the fastest possible clock rather than a clock that is off, so enforce a minimum value.
