hw/acpi/aml-build: Set identical implementation flag for PPTT processor nodes
Per ACPI 6.5 Table 5.158: Processor Structure Flags, the identical implementation flag indicates whether all the children processors of this node share the same identical implementation revision. Currently Linux support parsing this field [1] and maybe used to identify the heterogeneous platform. Since qemu only support homogeneous emulation, set this flag for all the processor node to indicates the facts when building the PPTT table. Node leaf is an exception since spec says this flag should be ignored on leaf nodes by OSPM.
