Subject: crypto: ccp - Add a header for multiple drivers to use `__psp_pa`

The TEE subdriver for CCP, the amdtee driver and the i2c-designware-amdpsp
drivers all include `psp-sev.h` even though they don't use SEV
functionality.

Move the definition of `__psp_pa` into a common header to be included
by all of these drivers.
