Telemetry: Fix issues in SCMI telemetry stack
- Extend SCMI_TELEMETRY_PROTOCOL_ATTRIBUTES() with a GROUP_SPECIFIC parameter so the bit is encoded alongside the other protocol flags.
- Build attributes_1 inside the protocol handler using SCMI_TELEMETRY_PROTOCOL_ATTRIBUTES(). adding the missing
num_shmti. - delete the dead scmi_telemetry_init_notifications() helper that only asserted because notifications are not implemented yet stop binding the SCMI notification API in scmi_telemetry_bind()
- Fix TDCF header metedata reset to zero
