Subject: [PATCH V7 5/5] phy: freescale: fsl-samsung-hdmi: Remove unnecessary LUT entries

The lookup table contains entries which use the integer divider
instead of just the fractional divider. Since the set and round
functions check both the integer divider values and the LUT values,
it's no longer necessary to keep the integer divider values in the
lookup table, as can be dynamically calcuated.
