binaryPI platforms: Drop any ACPI S3 support
No board with binaryPI currently supports HAVE_ACPI_RESUME. For platforms with PSP the approach is also very different from what we previously had here. Furthermore, s3_resume.[ch] files under cpu/amd/pi do not distinguish between NonVolatile and Volatile buffers of S3 storage. This means the Volatile buffer that is maintained and available in CBMEM is unnecessarily copied to SPI flash. This has been fixed on open-source AGESA directory, so development of S3 suspend support with binaryPI is better continued with that. Unfortunately there are further complications and indications that open-source AGESA may have always had a low-memory corruption issue. This has to be investigated separately before restoring or claiming S3 is supported on binaryPI.
