    mtd: aspeed: fix compile warning in aspeed_smc_read_from_ahb()
    
    The first argument of ioread32_rep() and ioread8_rep is not
    const. Change aspeed_smc_read_from_ahb() prototype to fix compile
    warning :
    
       drivers/mtd/spi-nor/aspeed-smc.c: In function 'aspeed_smc_read_from_ahb':
       drivers/mtd/spi-nor/aspeed-smc.c:212:16: warning: passing argument 1 of 'ioread32_rep' discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers]
          ioread32_rep(src, buf, len >> 2);
