Firmware handsoff specification withdraws "XOR" checksum usage and update the specification checksum calculation with "SUM" [0]. So the libtl also updates with this change [1] The "XOR" calculation was existed in v1, but as above mentioned, it's withdrown, and TF-A always gives the checksum with "SUM" calculation. Therefore, just update the xferlist version to 2.

The Firmware Handoff specification has withdrawn the use of the “XOR” checksum and updated the checksum calculation to use “SUM” [0]. Accordingly, libtl has also been updated to reflect this change [1]. The “XOR” checksum calculation existed in version 1; however, as mentioned above, it has been withdrawn, and TF-A always provides the checksum using the “SUM” calculation. Therefore, the xferlist version is updated to version 2.
