ipq806x: fix AP148 boot from NOR

Browse Source 
This patch allows AP148 to boot from NOR flash.

As we're using a FIT image as kernel (which includes kernel bin + DTB)
we enable the MTD_SPLIT_FIT_FW kernel option, which will detect the FIT
image and automatically split the "firmware" partition into 2 MTD parts
(kernel + rootfs).

The rootfs will then be parsed and split between rootfs + rootfs_data,
as usual.
