ARM: EXYNOS: Remove legacy dev- and setup- files
This patch removes now unused files containing old device and GPIO setup code that was needed for ATAGS based boot, which is not supported on Exynos any more. The only exception is setup-i2c0.c that will be removed later, since it has dependencies in plat-samsung/ directory.
