2a6170dfe7 crypto: ccp: Add Platform Security Processor (PSP) device support
The Platform Security Processor (PSP) is part of the AMD Secure
Processor (AMD-SP) functionality. The PSP is a dedicated processor
that provides support for key management commands in Secure Encrypted
Virtualization (SEV) mode, along with software-based Trusted Execution
Environment (TEE) to enable third-party trusted applications.

Note that the key management functionality provided by the SEV firmware
can be used outside of the kvm-amd driver hence it doesn't need to
depend on CONFIG_KVM_AMD.

d0ebbc0c40 crypto: ccp - rename ccp driver initialize files as sp device
CCP device initializes is now integerated into higher level SP device,
to avoid the confusion lets rename the ccp driver initialization files
(ccp-platform.c->sp-platform.c, ccp-pci.c->sp-pci.c). The patch does not
make any functional changes other than renaming file and structures
