spi: fsl-spi: Fix memory leak 

mpc8xxx_spi_probe() has set master->cleanup = mpc8xxx_spi_cleanup,
however current code overrides the setting in fsl_spi_probe() and set
master->cleanup = fsl_spi_cleanup.
Thus the memory allocated for cs is not freed anywhere.
Convert to use devm_kzalloc to fix the memory leak.
