hw/ssi/aspeed_smc: Allow 64-bit wide flash accesses

Browse source 
cde3247651 fixed atomicity for LDRD, which
ends up making accesses 64-bits wide. However, the AST2600 bootloader
can sometimes compile with LDRD instructions, which causes the acceses
to fail when accessing the memory-mapped SPI flash.

To fix this, increase the MMIO region valid access size to allow for
64-bit accesses.
