In order to support large number of vcpus, a newer 64-bit SMBIOS entry point type is needed. Therefore, upgrade the default SMBIOS version for PC machines to SMBIOS 3.0 for newer systems. Then increase the maximum number of vCPUs for Q35 models to 1024, which is the limit for KVM.
Changes from V5: (https://lore.kernel.org/qemu-devel/20230607024939.703991-1-suravee.suthikulpa...@amd.com/T/#m5a9f0d0e2355aebf81501355a1bf349a9929f4bb) * Patch 1: Get rid of pc_machine_init_smbios() and simplify the logic per Igor's suggestion. * Patch 2: Added reviewed-by tag.
