ARM: S5PV210: Add support for VPLL
This patch adds the following. 1. Adds 'clk_sclk_hdmi27m' clock to represent the HDMI 27MHz clock. 2. Adds 'clk_vpllsrc; clock of type clksrc_clk to represent the input clock for VPLL. 3. Adds 'clk_sclk_vpll' clock of type clksrc_clk to represent the output of the MUX_VPLL mux. 4. Add clk_sclk_hdmi27m, clk_vpllsrc and clk_sclk_vpll to the list of clocks to be registered. 5. Adds boot time print of 'clk_sclk_vpll' clock rate. 6. Adds 'clk_fout_vpll' clock to plat-s5p such that it is reusable on other s5p platforms.
