With this patch, it is at par with Exynos5250 and Exynos4 clocks where sclk_pixel ID is assigned to a divider clock but in real, sclk_pixel is listed under gate clocks (enum value).
Alternate to this, I can allocate a new ID, div_pixel, listed under new category of Divider Clocks for Exyno4, 5250 and 5420. div_pixel ID can be assigned to pixel clock dividers for all 3 SoCs. This ID can be accessed by hdmi driver as usual. While sclk_pixel ID can be left unused for Exyno4, 5250 as there are no pixel clock gates. And, For 5420, sclk_pixel can optionally be used to enable/disable the pixel clock gate.

sclk_pixel is used to represent pixel clock divider on all exynos SoCs not as a gate clock. It is queried in driver to pass as the parent to hdmi clock while switching between parents. A new ID can be asssigned Pixel gate clock which is currently not in use. Pixel clock gate is default 'on'.
