Using the SSRAM area size extracted by config_tools, the patch changes the hard-coded GPA SSRAM area size to its actual size, so that pre-launched VMs can support large(>8MB) SSRAM area. When booting service VM, the SSRAM area has to be removed from Service VM's mem space, because they are passed-through to the pre-rt VM. The code was bugged since it was using the SSRAM area's GPA in the pre-rt VM. Changed it to GPA in Service VM.
