hw/arm/aspeed_ast27x0-ssp: Add SDRAM region and fix naming and size to 512MB

Browse Source 
Previously, the SSP memory was incorrectly modeled as "SRAM" with
a 32 MB size. This change introduces a new sdram field in
AspeedCoprocessorState and updates the realization logic accordingly.
Rename from SRAM to SDRAM and correct size from 32MB to 512MB to match
hardware.
