cmd_writebcb_mx7: create FCB without errata e9609 work-around
Create a FCB without work-around for errata e9609. With that FCB
in place the firmware can be written using the standard nand write
command like:
nand write ${loadaddr} u-boot ${filesize}
Using sectors_in_firmware{1|2} seems not to make any difference and
is also not set on Vybrid, hence do not set it anymore.
