spi: Fix distinct pointer types warning for ARCH=mips 

Fix a new warning report by build for make ARCH=MIPS allmodconfig:

drivers/spi/spi-cadence-quadspi.c: In function 'cqspi_direct_read_execute':
 ./include/linux/minmax.h:18:28: warning: comparison of distinct pointer types lacks a cast
    18 |  (!!(sizeof((typeof(x) *)1 == (typeof(y) *)1)))
       |                            ^~
 ./include/linux/minmax.h:32:4: note: in expansion of macro '__typecheck'
    32 |   (__typecheck(x, y) && __no_side_effects(x, y))
       |    ^~~~~~~~~~~

"len" is unsigned,however,"500" is unsigned long.
