[PATCH 02/11] ARM: S5P6440: Change dout_mpll clock type to clksrc_clk clock type.

From: Thomas Abraham <thomas.ab at samsung.com>
This patch modifies the following.
1. Modifies the dout_mpll clock type as clksrc_clk clock type.
This modification allows the use of common clock code in
managing the dout_mpll clock (which otherwise would need
custom defined functions such as s5p6440_clk_doutmpll_get_rate).
2. s5p6440_clk_doutmpll_get_rate function is removed as it is
no longer needed.
