For a TX->TX connected external phy to transmit/receive data, the rgmii2
pin group needs to be claimed with gpio function, at least for EdgeRouter X
SFP. We already claim the pin group under the pinctrl node with gpio
function on the gpio node on mt7621_ubnt_edgerouter-x.dtsi.
However, we should claim a pin group under its consumer node. It's the
ethernet node in this case, which we already claim the rgmii2 pin group
under it on mt7621.dtsi. Therefore, set the function as gpio on the rgmii2
node for EdgeRouter X SFP and get rid of claiming the rgmii2 pin group
under the pinctrl node. With this change, we also get to remove a
definition from mt7621_ubnt_edgerouter-x.dtsi which is specific to
EdgeRouter X SFP.
This change is tested on an EdgeRouter X SFP.

Due to use of a script when migrating from mtd-mac-address, a few
of the definitions are redundant in DTSI and DTS files. Remove
those.

Define nvmem-cells and convert mtd-mac-address to nvmem implementation.
The conversion is done with an automated script.

Rework patch 681-NET-add-mtd-mac-address-support to implement
only the function to read the mac-address from mtd.
Generalize mtd-mac-address-increment function so it can be applied
to any source of of_get_mac_address.
Rename any mtd-mac-address-increment to mac-address-increment.
Rename any mtd-mac-address-increment-byte to mac-address-increment-byte.
This should make simplify the conversion of target to nvmem implementation.

The "/dts-v1/;" identifier is supposed to be present once at the
top of a device tree file after the includes have been processed.
In ramips, we therefore requested to have in the DTS files so far,
and omit it in the DTSI files. However, essentially the syntax of
the parent mtxxxx/rtxxxx DTSI files already determines the DTS
version, so putting it into the DTS files is just a useless repetition.
Consequently, this patch puts the dts-v1 statement into the top-level
SoC-based DTSI files, and removes all other occurences.
Since the dts-v1 statement needs to be before any other definitions,
this also moves the includes accordingly where necessary.

SFP cage of this device is connected via a AT8031 phy to port 5 of the switch.
This phy act as a RGMII-to-SerDes converter.
Also a I2C clock gate needs to be enabled in order to access the SFP module via I2C bus.
SFP cage also has module detect pin which is connected to I2C gpio expander.
With this patch the kernel/PHYLINK now can detect, readout and use the SFP module/port.
NOTE: SFP cage / AT8033 PHY only support 1000base-X encoding!
This means that some SGMII modules can work and only at forced 1GBit/full-duplex!

The "proper" vendor prefix for Ubiquiti is "ubnt", this is used in
all targets except ramips and also recommended by the kernel.
This patch adjusts the various board/image/device name variables
accordingly. Since we touch it anyway, this also adds the space
in "EdgeRouter X" as a hyphen to those variables to really make
them consistent with the model name.
While at it, create a real shared definition for the devices in
image/mt7621.mk instead of deriving one device from another.
