It set "aspeed_smc_flash_ops" struct which containing read and write callbacks to be used when I/O is performed on the SMC flash region. And it set the valid max_access_size 4 by default for all ASPEED SMC models.
However, the valid max_access_size 4 only support 32 bits CPUs. To support all ASPEED SMC model, introduce a new "const MemoryRegionOps *" attribute in AspeedSMCClass and use it in aspeed_smc_flash_realize function.
