The first 128 MiB of RAM can be accessed using an alias at address 0x0.
In theory we could access whole RAM using 0x80000000 - 0xbfffffff range
(up to 1 GiB) but it doesn't seem to work on Northstar. For some reason
(hardware setup left by the bootloader maybe?) 0x80000000 - 0x87ffffff
range can't be used. I reproduced this problem on:
1) Buffalo WZR-600DHP2 (BCM47081)
2) Netgear R6250 (BCM4708)
3) D-Link DIR-885L (BCM47094)
So it seems we're forced to access first 128 MiB using alias at 0x0 and
the rest using real base address + 128 MiB offset which is 0x88000000.

It was tested by LEDE users, all we need is to adjust clock frequency.
While we're at it create a separated DTS include file to share code with
other BCM4709 devices easier.

The NAND flash chip description were not imported for the Asus RT-AC87U
dts file when this was done for all the other dts files, because these
patches were send in parallel.
This adds a missing NAND flash chip description to this patch:
