Stefan Wahren 5b1f34bf36 spi: spi-fsl-lpspi: Adjust type of scldiv 
[ Upstream commit fa8ecda987 ]

The target value of scldiv is just a byte, but its calculation in
fsl_lpspi_set_bitrate could be negative. So use an adequate type to store
the result and avoid overflows. After that this needs range check
adjustments, but this should make the code less opaque.
