[PATCH 1/3] phy: freescale: fsl-samsung-hdmi: Expand Integer divider range

[Adam Ford]

The Integer divder uses values of P,M, and S to determine the PLL
rate.  Currently, the range of M was set based on a series of
table entries where the range was limited.  Since the ref manual
shows it is 8-bit wide, expand the range to be up to 255.
