platform/x86/intel/sdsi: Add in-band BIOS lock support
As per SDSi in-band interface specification, sec titled "BIOS lock for in-band provisioning", when IB_LOCK bit is set in control qword, the SDSI agent is only allowed to perform the read flow, but not allowed to provision license blob or license key. So add check for it in sdsi_provision(). Signed-off-by: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@linux.intel.com> Signed-off-by: David E.
