mpc5200: Add a4m2k board port
This patch adds the a4m2k MPC5200B board port. Its a derivate of the a3m071 board with only minor changes. Additionally this patch includes some clean-up changes: - Remove I2C support from a3m071 as its unused - Fix/enhance default env variables - Fix some comments - Add newly introduced CONFIG_SPL_TARGET to automatically build "u-boot-img.bin" - Fix dtb patching in READ desciption for SPL Linux booting: "fdt chosen" needs to get called to patch/create the chosen node. - Add missing call to spl_board_init(): Define CONFIG_SPL_BOARD_INIT so that spl_board_init() will get called in the SPL version.
