sbc8548: reclaim wasted sector in boot flash
By nature of being based off the MPC8548CDS board, this board inherited an ENV_SIZE setting of 256k. But since it has a smaller flash device (8MB soldered on), it has a native sector size of 128k, and hence the ENV_SIZE was causing 2 sectors to be used for the environment. By removing the unused sector, we can push TEXT_BASE up closer to the end of address space and reclaim that sector for any other application. This also fixes the mismatch between TEXT_BASE and MONITOR_LEN reported by Kumar earlier. Since this board also supports the ability to boot off the 64MB SODIMM flash, this change is forward looking with that in mind; i.e. the settings for MONITOR_LEN and ENV_SIZE will work when the 512k sectors of the SODIMM flash are used for alternate boot in the future.
