video: tegra: dc: fix hdmi mode filter
If there are more than one hdmi modes that have same xres,
yres, and vmode, tegra_dc_hdmi_mode_equal can return true even
though pixclocks are way different from each other.
Now, tegra_dc_hdmi_mode_equal will retun false if pixclock has
more than 1Hz of difference. Also, tegra_fb_set_par will use
fb_find_nearest_mode instead of fb_find_best_mode to take
refresh rate into the consideration.
Bug: 815409
