[PATCH v2 3/6] dt-bindings: crypto: Add Texas Instruments MCRC64

[Kamlesh Gurudasani]

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
