linux-headers: Update to include KVM_CAP_PPC_COMPAT_CAPS
Sync linux headers from Linux kernel commit 1200d84f4c0a
("Merge tag 'powerpc-7.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux").
This picks up the new KVM_CAP_PPC_COMPAT_CAPS capability for powerpc,
which introduces:
- struct kvm_ppc_compat_caps: reports processor compatibility modes
supported by the host (POWER9, POWER10, POWER11)
- KVM_PPC_GET_COMPAT_CAPS ioctl (KVMIO 0xb8)
- KVM_CAP_PPC_COMPAT_CAPS (cap #250) in linux/kvm.h
The sync is needed to get the corresponding Qemu series[1] merged.
