soc/amd/common/psp: Only set SPL fuses if an SPL file is present

Use the presence of an SPL (Software Patch Level) file to trigger the
function that reads and writes the SPL fuses. The current Kconfig
option will be used to decide to write the fuses. This allows us to
see the state of the SPL update bit which determines whether or not
SPL fusing is allowed and needed before enabling the fusing.

- Refactor a bit to prepare for following changes.
- Update phrasing
