Reboot the oxnas target based on Linux 4.14 by rebasing our support on
top of the now-existing upstream kernel support.
This commit brings oxnas support to the level of v4.17 having upstream
drivers for Ethernet, Serial and NAND flash.
Botch up OpenWrt's local drivers for EHCI, SATA and PCIe based on the
new platform code and device-tree.
Re-introduce base-files from old oxnas target which works for now but
needs further clean-up towards generic board support.

Functional issues:
 * PCIe won't come up (hence no USB3 on Shuttle KD20)
 * I2C bus of Akitio myCloud device is likely not to work (missing
   debounce support in new pinctrl driver)

Code-style issues:
 * plla/pllb needs further cleanup -- currently their users or writing
   into the syscon regmap after acquireling the clk instead of using
   defined clk_*_*() functions to setup multipliers and dividors.
 * PCIe phy needs its own little driver.
 * SATA driver is a monster and should be split into an mfd having
   a raidctrl regmap, sata controller, sata ports and sata phy.

Tested on MitraStar STG-212 aka. Medion Akoya MD86xxx and Shuttle KD20.

Calling nand_do_upgrade() from platform_pre_upgrade() was deprecated
with 30f61a34b4cf ("base-files: always use staged sysupgrade").

Update the platform upgrade code to use platform_do_upgrade() for NAND
images as well.

The watchdog kill command was meant for busybox watchdog. Busybox watchdog
was replaced by the procd watchdog mid 2013 with commit df7ce9301a25
("busybox: disable the watchdog utility by default"), which makes the kill
command obsolete since quite some time.

Use the generic function instead ot the target specific ones.

Now that we generate images with metadata attached, require it in order
to prevent accidentally flashing the wrong image to a board.

We're in process of cleaning nand_do_platform_check. Currently it leaves
a special mark in /tmp/sysupgrade-nand-path triggering some diffent code
path in nand_upgrade_stage1. This can be a bit confusing.

The plan is to have the check function only check the image and nothing
else. Then platform code (platform_pre_upgrade) should trigger NAND
specific upgrade path. This is what this patch implements.

This follows all other targets making it finally possible to change
nand_do_platform_check.

First of all platform_do_upgrade_phase2 doesn't seem to be defined
anywhere. Other than that platform_do_upgrade is not likely to be ever
called. There is a call to nand_do_platform_check which triggers
nand_upgrade_stage1 call with "exit 0" in it.

This is the oxnas target previously developed at
http://gitorious.org/openwrt-oxnas
Basically, this consolidates the changes and addtionas from
http://github.org/kref/linux-oxnas
into a new OpenWrt hardware target 'oxnas' adding support for
 PLX Technology NAS7820/NAS7821/NAS7825/...
formally known as
 Oxford Semiconductor OXE810SE/OXE815/OX820/...

For now there are 4 supported boards:
Cloud Engines Pogoplug V3 (without PCIe)
 fully supported

Cloud Engines Pogoplug Pro (with PCIe)
 fully supported

MitraStar STG-212
 aka ZyXEL NSA-212,
 aka Medion Akoya P89625 / P89636 / P89626 / P89630,
 aka Medion MD 86407 / MD 86805 / MD 86517 / MD 86587
 fully supported, see http://wiki.openwrt.org/toh/medion/md86587

Shuttle KD-20
 partially supported (S-ATA driver lacks support for 2nd port)
