aspeed/scu: Fix valid access size on AST2400
The read access size of the SCU registers can be 1/2/4 bytes and write is 4 bytes and all Aspeed models would need a .valid.accepts() handler. For the moment, set the min access size to 1 byte to cover both read and write operations on the AST2400 but keep the min access size of the other SoCs to 4 bytes as this is an unusual access size. This fixes support for some old firmware doing 2 bytes reads on the AST2400 SoC.
