    drivers/spi/spi-mpc52xx-psc.c:178:5: warning: no previous prototype for ‘mpc52xx_psc_spi_transfer_one_message’ [-Wmissing-prototypes]
      178 | int mpc52xx_psc_spi_transfer_one_message(struct spi_controller *ctlr,
	  |     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

mpc52xx_psc_spi_transfer_one_message() is only used inside the file that
defines it.  Hence fix this by making it static.
