smp_calculate_g2() function

* Function smp_calculate_g2 * Description The function calculates * g2(U, V, X, Y) = AES-CMAC (U||V||Y) mod 2**32 mod 10**6 * X * and * Vres = g2(U, V, X, Y) mod 10**6 * where * input: U is 256 bit, * V is 256 bit, * X is 128 bit, * Y is 128 bit, * Returns Vres. * Expected value has to be in the range [0 - 999999] i.e. [0 - 0xF423F]. * Vres = 1000000 means that the calculation fails. * Note The LSB is the first octet, the MSB is the last octet of * the AES-CMAC input/output stream.
