crypto: ccp - rename psp-dev files to sev-dev
This is a preliminary patch for creating a generic PSP device driver file, which will have support for both SEV and TEE (Trusted Execution Environment) interface. This patch does not introduce any new functionality, but simply renames psp-dev.c and psp-dev.h files to sev-dev.c and sev-dev.h files respectively.
