The value of I2C_TIMEOUT in fsl_i2c.c has several problems. First, it is
defined as CONFIG_HZ/4, but it is used as a count of microseconds, so it makes
no sense to derive it from a clock rate. Second, the current value (250) is
too low for some boards, so it needs to be increased. Third, the timeout
necessary for multiple-master arbitration is larger than the timeout for basic
read/write operations, so we shouldn't have a single constant for both timeouts.
Finally, it would be nice if we could override these values on a per-board
basis.
