Add binding for Texas Instruments MCRC64

MCRC64 engine calculates 64-bit cyclic redundancy checks (CRC)
according to the ISO 3309 standard.

The ISO 3309 64-bit CRC model parameters are as follows:
Generator Polynomial: x^64 + x^4 + x^3 + x + 1
Polynomial Value: 0x000000000000001B
Initial value: 0x0000000000000000
Reflected Input: False
Reflected Output: False
Xor Final: 0x0000000000000000
