As per new naming convention for Samsung SoC's, all Cortex-A9 and Cortex-A15 based SoC's will be classified under the name Exynos. Cortex-A9 and Cortex-A15 based SoC's will be sub-classified as Exynos4 and Exynos5 respectively. In order to better adapt and reuse code across various upcoming Samsung Exynos based boards, all uses of s5pc210 prefix/suffix/directory-names are renamed in this patch. s5pc210 is renamed as exynos4210 and S5PC210/s5pc210 suffix/prefix are renamed as exynos4/EXYNOS4.
