hw/arm/aspeed: Add machine properties to define the flash models
Some machines don't have much differences a part from the flash model
being used. Introduce new machine properties to change them from the
command line.
For instance, to start the ast2500-evb machine with a different FMC
chip and a 64M SPI chip, use :
-M ast2500-evb,fmc-model=mx25l25635e,spi-model=mx66u51235f
