This patch series mainly updates SapphireRapids CPU model and adds new
CPU model GraniteRapids.

Bit 13 (ARCH_CAP_SBDR_SSDP_NO), bit 14 (ARCH_CAP_FBSDP_NO) and bit 15
(ARCH_CAP_PSDP_NO) of MSR_IA32_ARCH_CAPABILITIES are enumerated starting
from SapphireRapids, which are missed in current SapphireRapids CPU model,
so add a new version for SapphireRapids CPU model to expose these bits.

GraniteRapids is Intel's successor to EmeraldRapids, an Intel 3 process
microarchitecture for enthusiasts and servers, which adds new features
based on SapphireRapids. The new features can be found in [1].
