Subject: ipq806x: add NAND flash controller support
These patches add support for ipq806x NAND flash controller. Most of
these are cherry-picked & backported from LKML:
*https://lkml.org/lkml/2015/8/3/16
This patch just modifies the kernel code, but doesn't change the config.
It should be harmless.
