[PATCH 1/2] ARM: imx/bbu-external-nand: Rename offset -> nand_offset

[Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx>]

The next commit introduces a new offset variable for image. To be better
able to differentiate the two, pick a better name for the already
existing one. There is no functional change.
