i2c: stm32f7_i2c: allows for any bus frequency

2020-03-24T13:23:32Z

Do not limit to 3 (100KHz, 400KHz, 1MHz) bus frequencies, but instead allow for any frequency. Depending on the requested frequency (via the clock-frequency DT entry), use the spec data from either Standard, Fast or Fast Plus mode. In order to do so, the driver do not use anymore spec identifier by directly handle the requested frequency and from it retrieve the corresponding spec data to be used for the computation of the timing register.
