mtd: support ONFI multi lun NAND

With onfi a flash is organized into one or more logical units (LUNs).
A logical unit (LUN) is the minimum unit that can independently execute
commands and report status.

Mtd does not exploit LUN, so make it see a big single flash where size is
lun_size * number_of_lun.

Without this patch MT29F8G08ADBDAH4 size is 512MiB instead of 1GiB.

Artem: split long line on 2 shorter ones.

This is commit 637957551c0ac80de8dfc7650d320c5a98c2c0c0 from Linux
