platform/x86:intel/vsec: Change return type of intel_vsec_register 



Change return type of intel_vsec_register() to int. The current
implementation does not indicate if the register fail or not.
Change to return error code if it fails or if INTEL_VSEC config
is not set. This is a preparation step to introduce a new SSRAM
Telemetry driver that will be using this API.
