i2c: s3c24x0: reduce transmission status timeout

If no device is connected to I2C bus, the i2c probe command
can take a lot of time for probe each address. This commit
reduces the busy timeout to 10ms for standard and high speed
modes. This doesn't break the transmission an also allow for
properly probe the devices.
