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

 5. Save fdt to NOR flash:

 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
