LAFW shenanigans.
* Added custom key sources to derive CardInfo keys at runtime using SPL. * Implemented CardInfo area decryption. * Implemented LAFW blob lookup in FS .data segment to retrieve the current LAFW version. P.S.: still need to move around code to perform the LAFW version check at the places we need. But the current code is good enough for a test.
