clk: samsung: exynos5260: Move struct samsung_cmu_info to init section
    
 This patch moves the samsung_cmu_info struct instances to initconst section,
 this decreases the kernel image size by 784 bytes, which makes zImage smaller
 by 480 bytes.
    
 The patch increases .init.rodata section size by 780 bytes but decreases
 .init.text section size by 1564 bytes.
    
 Size of the drivers/clk/samsung/clk-exynos5260.o object file is 29100 bytes
 without the patch and 28316 after applying the patch.
    
 The section size differences are as below:
 15c15
 <   3 .init.text    000006b8  00000000  00000000  00000034  2**2

 <   8 .init.rodata  00003f6c  00000000  00000000  00002f20  2**2
