[GIT PULL] KVM: x86: SVM changes for 6.17

[Sean Christopherson <seanjc@google.com>]

Two small SNP changes.  I initially balked at completely dropping KVM's checks,
but I can't think of any way this will cause ABI problems, and I also don't see
how having KVM perform checks would add value in any way.  So here they are :-)

The following changes since commit 28224ef02b56fceee2c161fe2a49a0bb197e44f5:

  KVM: TDX: Report supported optional TDVMCALLs in TDX capabilities (2025-06-20 14:20:20 -0400)

  KVM: SVM: Allow SNP guest policy to specify SINGLE_SOCKET (2025-06-20 13:33:45 -0700)

----------------------------------------------------------------
KVM SVM changes for 6.17

Drop KVM's rejection of SNP's SMT and single-socket policy restrictions, and
instead rely on firmware to verify that the policy can actually be supported.
Don't bother checking that requested policy(s) can actually be satisfied, as
an incompatible policy doesn't put the kernel at risk in any way, and providing
guarantees with respect to the physical topology is outside of KVM's purview.
