mpc5200: Misc updates to a3m071 config header
This patch changes some features of the a3m071/a4m2k board support: - Add bootcounter support - Update MTD env default to correct values - Add mtdparts to bootargs for mtd partitioning via kernel cmdline - Added some default env variables for easy updating (kernel, dtb) - Change README to the updated flash locations Signed-off-by: Stefan Roese <sr@denx.de>

All this can be integrated into an environment command:
-=> setenv upd_fdt 'tftp 1800000 a3m071/a3m071.dtb;run mtdargs addip2 addtty; \
- fdt addr 1800000;fdt boardsetup;fdt chosen;erase fc060000 fc07ffff; \

=> saveenv
After this, only "run upd_fdt" needs to get called to load, patch
