hw/arm/aspeed_ast27x0.c Fix boot issue for AST2700

Browse source 
Currently, ASPEED_DEV_SPI_BOOT is set to "0x400000000", which is the DRAM start
address, and the QEMU loader is used to load the U-Boot binary into this address.

However, if users want to install FMC flash contents as a boot ROM, the DRAM
address 0x400000000 would be overwritten with Boot ROM data. This causes the
AST2700 to fail to boot because the U-Boot data becomes incorrect.

To fix this, change the ASPEED_DEV_SPI_BOOT address to "0x100000000", which is
the FMC0 memory-mapped start address in the AST2700.
