ACPI / processor: Make it possible to get local x2apic id via _MAT
Logical processors with APIC ID values of 255 and greater are required to have a Processor Device object and must convey the processor's APIC information to OSPM using the Processor Local X2APIC structure, but not until ACPI 5.1, X2APIC structure was not supported in _MAT method. _MAT is needed for CPU hotplug and system with more than 255 CPUs will definitely need X2APIC structure, so add its support in map_mat_entry() to make it possible to get local x2apic id via _MAT based on ACPI 5.1.
