dm: get lapic id from madt

Browse Source 
The GET_PLATFORM_INFO will be removed from hypervisor. The acrn-dm can
only refer to Service VM's resources from now, all the resources out of
Service VM are not awared by acrn-dm. The original info got from
GET_PLATFORM_INFO needs to changed to Service VM's perspective like lapic id.

The pcpu_id is the index of lapic instance in MADT table. This patch
parses the Service VM's MADT table to convert the pcpu_id to lapic_id instead
of GET_PLATFORM_INFO.
