[U-Boot] [PATCH 3/5] Exynos5: Fix rpll_sdiv to support both peach-pit and peach-pi panels

[Ajay Kumar]

The existing setting for rpll_sdiv generates 70.5Mhz RPLL
video clock to drive 1366x768 panel on peach_pit.

This clock rate is not sufficient to drive 1920x1080 panel on peach-pi.
So, we adjust rpll_sdiv to 3 so that it generates 141Mhz pixel clock
which can drive peach-pi LCD.

This change doesn't break peach-pit LCD since 141/2=70.5Mhz, i.e FIMD
divider at IP level will get set to 1(the required divider setting
will be calculated and set by exynos_fimd_set_clock()) and hence
peach-pit LCD still works fine.
