Currently the 'big-endian' property is listed as required, which is not correct. i.MX SoCs do not need such property, so move it under 'Optional properties' entry instead.
Also, fsl-sai.txt incorrectly referenced 'FTM_PWM registers', so change it to 'SAI registers', which is the intended description.
