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.

Minor nit, for next time: the copyright dates should be <first
year>,<current year>. I got this wrong the last time I updated it. :-(
The change above, for sev-dev.c, is correct.
