E1xx should skip bad blocks in NAND during upgrade write

This commit increases the E1xx's bootloader version to v2.1.0

This bootloader fixes an error in bad-block handling that would
result in the device boot-looping in the bootloader during a Firmware
upgrade if there is a bad block in the rootfs partition.
