drivers/fsp2: Don't print garbage if the FSP signature doesn't match

Using a &uint64_t as a string argument does not include the required
NULL character termination. Update the format string to only print the 8
desired characters and not continue printing stack memory until a NULL
is found.

Before:
[EMERG]  Invalid UPD signature! FSP provided "AMD_01_M;....`", expected was "CEZANE_MAMD_01_M;....`".

After:
[EMERG]  Invalid UPD signature! FSP provided "AMD_01_M", expected was "CEZANE_M".
