stm32/i2c: Make timeout for hardware I2C configurable.
Previously the hardware I2C timeout was hard coded to 50ms which isn't
guaranteed to be enough depending on the clock stretching specs of the I2C
device(s) in use.
This patch ensures the hardware I2C implementation honors the existing
timeout argument passed to the machine.I2C constructor. The default
timeout for software and hardware I2C is now 50ms.
