agesawrapper.c: check if HOP_COUNT_TABLE exists before AmdInitLate() 

If HOP_COUNT_TABLE doesn't exist AmdInitLate() returns error when
creating CDIT, which scaries users. This patch turns off CDIT generation.

After this patch AGESA_UNSUPPORTED is returned due to a bug in
AGESA which cannot be walked around without disabling DMI table
generation (`AGESA_STATUS Status = TRUE`, present in open source
version of AGESA too).
