ba3d92c5a0 ramips: convert most mtd-mac-address cases in DTSI to nvmem
Convert most of the cases from mtd-mac-address to nvmem where
MAC addresses are set in the DTSI, but the partitions are only
located in the device DTS. This posed some problems earlier, since
in these cases we are using partitions before they are defined,
and the nvmem system did not seem to like that.

There have been a few different resolution approaches, based on
the different tradeoffs of deduplication vs. maintainability:

 1. In many cases, the partition tables were identical except for
    the firmware partition size, and the firmware partition was
    the last in the table.
    In these cases, the partition table has been moved to the
    DTSI, and only the firmware partition's "reg" property has
    been kept in the DTS files. So, the updated nvmem definition
    could stay in the DTSI files as well.

 2. For all other cases, splitting up the partition table would
    have introduced additional complexity. Thus, the nodes to be
    converted to nvmem have been moved to the DTS files where the
    partitioning was defined.

 3. For Netgear EX2700 and WN3000RP v3, the remaining DTSI file
    was completely dissolved, as it was quite small and the name
    was not really nice either.

 4. The D-Link DIR-853 A3 was converted to nvmem as well, though
    it is just a plain DTS file not taken care of in the first
    wave.

In addition, some minor rearrangements have been made for tidyness.

Not covered (yet) by this patch are:

 * Various unielec devices
 * The D-Link DIR-8xx family

66d12ce667 ramips: remove redundant status for USB controllers
mt7621, mt7628an and rt5350 have USB controllers (ehci/ohci or xhci)
enabled by default. Thus, this patch drops redundant status=okay
statements in derived device DTS files.

While at it, also drop an explicit status=okay in mt7621.dtsi, as
this is default.

Note:

For rt5350, about 50 % of the devices enabled ehci/ohci in the DTS
files, and there is actually no device actively disabling it.
It looks like only a few people are aware that the controllers are
enabled by default here.

b756ea2a90 ramips: replace pinctrl property names
Upstream pinctrl driver in drivers/staging uses
groups/function/ralink,num-gpios instead of
ralink,group/ralink,function/ralink,nr-gpio
Replace these properties in dts as well as the pinctrl driver in
patches-4.14.

e4ce3109f2 ramips: simplify state_default/pinctrl0 in device DTS files
The node pinctrl0 is already set up in the SOC DTSI files, but
defined again as member of pinctrl in most of the device DTS(I)
files. This patch removes this redundancy for the entire ramips
target.

a2c19f1d2f ramips: dts: drop memory nodes
mt7621 and mt7628 now have the ability to detect memory size
automatically.
Drop memory nodes and let kernel determine memory size.
