[PATCH v2 3/5] hw/arm/aspeed_ast27x0-fc: Map ca35 memory into system memory

[Steven Lee via]

Attach CA35 memory to system_memory to ensure a valid FlatView.
Without this, dma_memory_write() used by ftgmac fail silently,
causing dhcp to break on ast2700fc, as flatview_write() returns
an error when system_memory is empty.
