cmd_nand: add nand write.trimffs command
Add another nand write. variant, trimffs. This command will request of
nand_write_skip_bad() that all trailing all-0xff pages will be
dropped from eraseblocks when they are written to flash as-per the
reccommended behaviour of the UBI FAQ [1].
The function that implements this timming is the drop_ffs() function
by Artem Bityutskiy, ported from the mtd-utils tree.
