target-i386: Sanitize AMD's ext2_features at realize time
When CPU properties are implemented, ext2_features may change between object_new(CPU) and cpu_realize_fn(). Sanitizing ext2_features for AMD based CPU at realize() time will keep current behavior after CPU features are converted to properties.
