NOTE: skipped v3 to avoid confusing...
Changes since v2:
-Fixed on following...
The shift bit of 'S5P_CLKSRC_CPU' register for clksrc_clk 'clk_mout_mpll'
The 'S5P_CLKSRC_CORE' register for clksrc_clk 'clk_mout_corebus'
The 'S5P_CLKSRC_TOP1' register for clksrc_clk 'clk_vpllsrc'
Added S5P_CLKSRC_CORE definition.
- Modified some wrong clock names.
- CodingStyle fixes...
