install_linux_fw_sd: erase NAND partitions before update 

NAND partitions may have pre-existing UBI volume information
and that will tell U-Boot to use 'ubiwrite' to keep UBI wear
leveling information instead of erasing the NAND partition
beforehand. Given that the UBI support in U-Boot is not
particularly complete and stable, and specially if the NAND
partition table has been changed, this could result into
problems during the UBI volume initialization or during the
update process. To prevent such problems it is better that
the NAND partitions are erased.

This loses the UBI wear leveling information but provides
a more reliable deployment install script.
