stm32: i2c: drop useless integer defines I2C_CR2_FREQ_

Browse Source 
These defines were simply a word containing the number, instead of the
number itself.  This provides no value, and implies that there's a
limited set of values.  The list was _already_ incomplete, so
misleading, _and_ just noise to maintain.  Burn it all.

(well, burn it just a little bit, provide deprecated aliases on the old
values so that code keeps compiling)
