fsl_dspi: set scaler values for CS-SCK and SCK-CS delays

These values were calculated but not set.
They are required for the calculation of the delays, as stated in the
"QorIQ LS1043A Reference Manual, Rev. 6, 07/2020" page 2172.

The delays are calculated as (1/freq)*PCSSCK*CSSCK and
(1/freq)*PASC*ASC.
