aspeed/sdmc: Check RAM size value at realize time 

The RAM size of the SDMC device is validated for the SoC and set when
the Aspeed machines are initialized and then later used by several
SoC implementations. However, the SDMC model never checks that the RAM
size has been actually set before being used. Do that at realize.
