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
