i2c: exynos5: change internal transmission timeout to 100ms
Exynos-I2C uses default timeout of 1 second for the whole transaction, including re-transmissions due to arbitration lost errors (-EAGAIN). To allow re-transmissions driver's internal timeout should be significantly lower, 100ms seems to be good candidate.
