[PATCH] i2c: stm32f7_i2c: save some ms in stm32_i2c_choose_solution

[Richard Genoud]

In stm32_i2c_choose_solution, the double loop continues even after a
solution is found.

Breaking out of this double loop once a solution is found permits to
gain some precious ms.

This saves about 13ms in U-Boot.
