[PATCH] i2c i.MX: Fix divider table

[Sascha Hauer]

Measurements on i.MX1 and i.MX53 have shown that the divider values
in the datasheets are wrong. the values from first, third and fourth
column were all measured to be 8 higher than in the datasheet. It
should be safe to assume that the SoCs between i.MX1 and i.MX53 behave
the same as the i2c unit is unchanged since the i.MX1.
