HV: add acpi module support for pre-launched VM

Browse Source 
Previously we use a pre-defined structure as vACPI table for pre-launched
VM, the structure is initialized by HV code. Now change the method to use a
pre-loaded multiboot module instead. The module file will be generated by
acrn-config tool and loaded to GPA 0x7ff00000, a hardcoded RSDP table at
GPA 0x000f2400 will point to the XSDT table which at GPA 0x7ff00080;
