[PATCH 1/2] hw/arm/aspeed: allow missing spi_model

[Patrick Williams]

Generally all BMCs will use the fmc_model to hold their own flash
and most will have a spi_model to hold the managed system's flash,
but not all systems do.  Add a simple NULL check to allow a system
to set the spi_model as NULL to indicate it should not be instantiated.
