spi: hisi-kunpeng: Fix Woverflow warning on conversion 



Fix warning Woverflow on type conversion reported on x86_64:

  drivers/spi/spi-hisi-kunpeng.c:361:9: warning: conversion from 'long unsigned int' to 'u32'
  {aka 'unsigned int'} changes value from '18446744073709551600' to '4294967280' [-Woverflow]

The registers are 32 bit, so fix by casting to u32.
