These come fromm using '/' instead of one of the kernel's DIV macros when using
u64 or ULL  data types.

in mlxbf_i2c_get_ticks():

	ticks = (nanoseconds * frequency) / MLXBF_I2C_FREQUENCY_1GHZ;

in mlxbf_i2c_calculate_freq_from_yu():

	corepll_frequency = (MLXBF_I2C_PLL_IN_FREQ * core_f) / MLNXBF_I2C_COREPLL_CONST;
	corepll_frequency /= (++core_r) * (++core_od);

in mlxbf_i2c_calculate_freq_from_tyu():

	core_frequency /= (++core_r) * (++core_od);
