cmd_writebcb_mx7: remove errata e9609 specific command writeboot

The writeboot command has been used to write the bootloader in
a format required by early boot ROM's do to errata e9609 (write
3/4 of a page only). Since U-Boot now writes also BCBs which use
the full page, we can use standard U-Boot nand write commands to
write the bootloader.
