vendorcode/amd/pi/00670F00: Remove S3 restore functions

These functions are not currently used, and were not in the original
AGESA source code drop.

The structs involved here were marked "private" in AGESA headerfiles
and should not be exposed. They could be handled as anonymous structs
and required allocation size is communicated by other means.

BUG=b:64766233
TEST=Build in cros tree and upstream coreboot, with old headers
and updated headers.
