BTW we do have that taken care. spi_mem_adjust_op_size will
adjust the transfer size according to max_transfer/message_size
if no custom adjust_op_size hook is defined in the driver. If a custom
adjust_op_size is defined, the driver adjusts the transfer size for it's
exec_op hook. The size limit between exec_op and transfer_one_message
can be different. (this spi-mtk-nor is an example of that.)
