[PATCH 00/13] Add support for Lenovo ix4-300d NAS

[Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com>]

This patch set adds support for the Lenovo ix4-300d NAS based on
Marvell Armada XP MV78230 SoC. Unfortunately, this very SoC has
a broken SoC-Id and wrongly indentifies itself as MV78460 instead.
Marvell's BSP u-boot fixes this by overwriting the PCI ID register
that is used by Linux for SoC identification with the correct value,
so we also add a proper fixup.

Stuff that is already working on ix4:
- Front USB port on xHCI PCI
- Both GbEs (with txdesc fix for mvneta) on 88E1318S PHYs
- LEDs and buttons

Missing functions:
- Front GLCD (I started a driver but have to have another look at it)
- Back USB on internal controllers (missing CI glue logic and USB PHY
  for Armada XP, have some old patches for KW and Dove)
- 88SX7042 4-port SATA controller on PCIe x4 (nothing here)
- NAND flash (hope Ezequiel finds some time here)
- External RTC, Fan control (nothing here)

Patches 1-4 add support for Marvell 88E1318S PHYs, 74x164 used as
GPIO expander, and bitbang SPI.

Patches 5-7 cleanup and convert mvebu-mbus driver from a
postcore-registered driver to be directly called from mvebu SoC
init which allows to setup mbus windows before any drivers.

Patches 8-9 install a fixup function for Armada 370/XP SoCs to
fake a correct SoC Id for broken MV78230 SoCs.

Patches 10-12 cleanup Armada 370/XP code prior to adding support
for Lenovo ix4-300d in Patch 13.
