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.

This was caused probably by a typo while the common interrupts definition was refactored. This patch moves timer interrupt range to safe area of 11-15 (just before uart range). This fixes the commit 87aef30eb3c5dac0491c83fe3b90bc61f1df24ec ("ARM: S5P: Change S5P_TIMER_IRQ based to 11 for SAMSUNG S5P series.") which meant to move these into the old (and previously reserved) ISA space.
