[PATCH 03/17] spi: fsl: Use kcalloc() 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 reuse the corresponding function "kcalloc".

This issue was detected by using the Coccinelle software.
