CRC hack entries

Some new CRCs.

Clarified and corrected some regioncodes.

Removed "same CRC as EU {0x6BA2F6B9, ResidentEvil4, NoRegion, 0}," & "same CRC as US {0xD6385328, GodOfWar, NoRegion, 0},".
There might (or not) be another disc (of an unknown region) that has the same CRC.
The same speculation could be made about all entries; it's only confusing.

Disabed the entries which have the same CRC as discs of other games (else there is bound to be problems).
