Add support for the Sercomm AD1018 router

This a BCM6328 based board, 128 MB RAM, 128 MiB NAND flash,
with an onboard BCM43217 wifi, 4 ethernet ports and 1 USB
host port (not soldered). The board also has an FXS chip (Si32177)
connected via SPI (SS2#), without support in LEDE.

Since NAND flash chips aren't still supported in brcm63xx, the
support is for now added to work only with SPI flash chips. Therefore
hardware modding, soldering a new SPI flash chip, is required
to make the board work with LEDE (tested and working OK).
The flash at dts is intentionally left without partitioning to let
the user choose a NOR chip of any size (8, 16 or 32 MB).
