[RFC] update: Add eccmode switching for different types

[Jan Weitzel]

to use update on nand with different eccmodes for the nand partitions
we need to set the eccmode before updating.
Adding eccdev and eccmode to enviroment to use.
eccdev example: gpmc_nand0
eccmode for the different types:
root_eccmode
barebox_eccmode
bareboxenv_eccmode
xload_eccmode
