powerpc/mpc8536ds: Save the env variables to SDcard and SPI flash
MPC8536DS offer booting from SDcard or SPI flash. This patch defined that u-boot can save the environment variables on SDcard or SPI flash when booting from the related device. The Env parameter region and linux kernel region have overlap in SPI-Flash, So change the Env param saving address.
