Fix the following coccicheck warnings:
drivers/spi/spi-au1550.c:408:21-22: WARNING opportunity for min()
drivers/spi/spi-au1550.c:542:21-22: WARNING opportunity for min()
min() macro is defined in include/linux/minmax.h. It avoids multiple
evaluations of the arguments when non-constant and performs strict
type-checking.
