stm32/boards/NUCLEO_F429ZI: Enable I2C1 and I2C2 with default pins.

Browse Source 
The datasheet on page 55 shows PF0 (SDA) and PF1 (SCL) are the pins for
I2C2, but these pins do not work.  Checking the MBED pinout for the
NUCLEO-F429ZI shows:

    I2C1: PB8 (SCL) and PB9 (SDA).
    I2C2: PB10 (SCL) and PB11 (SDA).

Both of these work and can be scanned and find devices connected to them.
