hw/arm/virt-acpi-build: Fix wrong size of flash in ACPI table
While virt machine creates two flash devices with total size 0x08000000, the ACPI table generation code was wrongly using this total size as the size of each flash device, so it would overlap other MMIO spaces. Make each device entry in the table half the total; this brings the ACPI table into line with the code which generates the device tree and which creates the flash devices themselves.
