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.
