Supports both FDT and non-FDT. This patch creates a new file 'exynos5-dt.c' meant for FDT support. exynos5-dt.c: This file shall contain all code which supports FDT. Any addition of FDT support for any module needs to be added in this file. smdk5250.c: This file shall contain the code which supports non-FDT. version. Any addition of non-FDT support for any module needs to be added in this file. May be, the file smdk5250.c can be removed in near future when non-FDT is not required. The Makefile is updated to compile only one of the files exynos5-dt.c / smdk5250.c based on FDT configuration. NOTE: Please note that all additions corresponding to FDT need to be added into the file exynos5-dt.c. At same time if non-FDT support is required then add the corresponding updations into smdk5250.c.
