GET_PLATFORM_INFO interface will be removed from ACRN hypervisor, Service VM /ACRN-DM and other userland applications shall not use it any more. For dm the lapic id was get from acrn_platform_info. So in version 2.7, SOS madt table is parsed to get the lapic id for each pcpu. There has an assumption. The SOS owned pcpu starts from physical cpu 0, otherwise SOS doesn't know the mapping relationship between its vcpu0 and pcpu_id.
