clk/exynos5250: add mout_hdmi mux clock for hdmi
hdmi driver needs to change the parent of hdmi clock
frequently between pixel clock and hdmiphy clock. hdmiphy is
not stable after power on and for a short interval while changing
the phy configuration. For this duration pixel clock is used to
clock hdmi.
This patch is exposing the mux for changing parent.
