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.
