Add the definitions needed by the upcoming VSM / VTL1 bring-up code:
- HV_ACCESS_VSM and HV_ACCESS_VP_REGS partition privilege bits
- HVCALL_ENABLE_PARTITION_VTL and
HVCALL_MODIFY_VTL_PROTECTION_MASK hypercall IDs
- hv_input_enable_partition_vtl input structure and its flags union
- hv_register_vsm_{partition_status,vp_status} register layout unions
- HV_REGISTER_VSM_PARTITION_STATUS and
HV_REGISTER_VSM_VP_SECURE_CONFIG_VTL0 register names
Definitions taken from the Hyper-V TLFS.
