spi: fsl: Use kmalloc_array() in of_fsl_spi_get_chipselects()
A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus use the corresponding function "kmalloc_array".
This issue was detected by using the Coccinelle software.
