Roger Pau Monné 0f640366e5 x86/spec-ctrl: Expose BHI_CTRL to guests
The CPUID feature bit signals the presence of the BHI_DIS_S control in
SPEC_CTRL MSR, first available in Intel AlderLake and Sapphire Rapids CPUs

Xen already knows how to context switch MSR_SPEC_CTRL properly between guest
and hypervisor context.
