phy: freescale: fsl-samsung-hdmi: Fix 64-by-32 division cocci warnings
The Kernel test robot returns the following warning:
do_div() does a 64-by-32 division, please consider using div64_ul instead.
To prevent the 64-by-32 divsion, consolidate both the multiplication
and the do_div into one line which explicitly uses u64 sizes.
Fixes: 1951dbb41d1d ("phy: freescale: fsl-samsung-hdmi: Support dynamic integer")
