Alexey Kardashevskiy 4be423572d crypto/ccp: Implement SEV-TIO PCIe IDE (phase1)
Implement the SEV-TIO (Trusted I/O) firmware interface for PCIe TDISP
(Trust Domain In-Socket Protocol). This enables secure communication
between trusted domains and PCIe devices through the PSP (Platform
Security Processor).

The implementation includes:
- Device Security Manager (DSM) operations for establishing secure links
- SPDM (Security Protocol and Data Model) over DOE (Data Object Exchange)
- IDE (Integrity Data Encryption) stream management for secure PCIe

This module bridges the SEV firmware stack with the generic PCIe TSM
framework.

This is phase1 as described in Documentation/driver-api/pci/tsm.rst.

On AMD SEV, the AMD PSP firmware acts as TSM (manages the security/trust).
The CCP driver provides the interface to it and registers in the TSM
subsystem.

Detect the PSP support (reported via FEATURE_INFO + SNP_PLATFORM_STATUS)
and enable SEV-TIO in the SNP_INIT_EX call if the hardware supports TIO.

Implement SEV TIO PSP command wrappers in sev-dev-tio.c and store
the data in the SEV-TIO-specific structs.

Implement TSM hooks and IDE setup in sev-dev-tsm.c.
