New 3DS ARM9 process 9 Decryption for cfw

Because GateWay can fuck right  off!!!!

1) Get the SHA256 of 0x10012000-0x10012090.
2) Initialize Keyslot-0x11 with KeyX being the lower portion of the hash, and KeyY the higher one... This keyslot is now consloe-unique
3) Read NAND sector 0x96 (NAND image offset 0x12C00) with size 0x200 bytes. Decrypt the first 0x10 bytes with Keyslot-0x11 and AES-ECB.
4) Clear Keyslot-0x11's KeyX, KeyY, and normal-key.
5) Set Keyslot-0x11's normal key to the data decrypted from nand.
6) decrypt arm9_bin_buf+0 with AES-ECB, use that for Keyslot-0x15's keyX....
7) Keyslot-0x15's keyY is arm9_bin_buf+16
8) ctr is arm9_bin_buf+332
9) decrypt with 0x15 and aes-ctr!!!!!!!!!!
