This patch updates existing macros, functions used for TI816X, to enable addition of other SoCs belonging to TI81XX family (e.g., TI814X). The approach taken is to use TI81XX/ti81xx for code/data going to be common across all TI81XX devices. cpu_is_ti81xx() is introduced to handle code common across TI81XX devices. In addition, ti8168_evm_map_io() is now replaced with ti81xx_map_io() and moved in mach-omap2/common.c as same will be used for TI814X and is not board specific.
