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 V3:
(https://lore.kernel.org/qemu-devel/20230603032255.517970-1-suravee.suthikulpanit@amd.com/T/#t )
 * Patch 1: Refactor the code to setup SMBIOS defaults to pc_machine_done().
 * Patch 2: Minor typo fixes in comment.

Changes from V2:
(https://lore.kernel.org/qemu-devel/20230531225127.331998-1-suravee.suthikulpanit@amd.com/)
 * Add patch 1.

Changes from V1:
(https://lore.kernel.org/all/YnkDGsIi1vFvXmiP@redhat.com/T/)
 * Bump from 512 to KVM_MAX_VCPUS (per Igor's suggestion)

Thank you,
Suravee
