spi: spi-fsl-lpspi: Clamp too high speed_hz
Currently the driver is not able to handle the case that a SPI device
specifies a higher spi-max-frequency than half of per-clk:
per-clk should be at least two times of transfer speed
Fix this by clamping to the max possible value and use the minimum SCK
period of 2 cycles.
