Remove extra (and wrong) I2C ByteTimeout setting in DDC code.

The DDC code sets the I2C timeouts to VESA standards, except that it had an
extra setting of the ByteTimeout value which was wrong (off by a factor of
50). Removing this should help DDC work on many more monitors. Note that the
Intel driver duplicated these settings, along with the error. Yay for cult
and paste coding.
