The unimplemented memory region overlaps with the VBootROM address
range, causing incorrect memory layout and potential behavior issues.
This patch adjusts the size and start address of the unimplemented
region to avoid collision. The IO memory region (ASPEED_DEV_IOMEM) is
now moved to 0x20000 to reserve space for VBootROM at 0x0.
