i2c: i2c-stm32f7: improve loopback in timing algorithm

Browse source

This avoids useless loops inside the I2C timing algorithm.
Actually, we support only one possible solution per prescaler value.
So after finding a solution with a prescaler, the algorithm can
switch directly to the next prescaler value.
