ARM: S5P6440: Register apll/mpll/epll mout clocks.

Browse Source 
This patch modifies the following.

1. Registers the mout_apll clksrc_clk clock.

2. The mout_mpll and mout_epll were registered as 'struct clk'
   types and then their parents were setup using the s3c_set_clksrc
   function. This patch reduces the two steps into one by registering
   the mout_mpll and mout_epll clocks using the s3c_register_clksrc
   function.

3. As per point 2 above, the init_parents array is no longer required.
   So the mout clocks are now put together in a new array named 'sysclks'.
   The sysclks array will list the system level clocks and more
   clocks will be added to it in the subsequent patches.
