The Ralink GPIO driver supports irqchip function. Hence we need to
add "interrupt-parent" and "interrupt-controller" properties to make
sure it works properly. It is worth noting that all GPIO devices
share the same interrupt line.

base seems come from the kernel symbol CONFIG_GPIOLIB_FASTPATH_LIMIT.

Use reset controller to reset mt7620 ethernet phy instead of directly
writing system control registers. The reset line of "ephy" is 24, so
the DTS resets properties have been updated to get the correct reset
signal.
Tested on HiWiFi HC5861.

These nodes are used for configuring a GMAC interface
and for defining external PHYs to be accessed with MDIO.
None of this is possible on MT7620N, only MT7620A,
so remove them from all MT7620N DTS.
When the mdio-bus node is missing, the driver returns -NODEV
which causes the internal switch to not initialize.
Replace that return so that everything works without the DTS node.
Also, an extra kernel message to indicate for all error conditions
that mdio-bus is disabled.

There are only 2 options in the driver
for the function of mt7620 internal switch port 4:
EPHY mode (RJ-45, internal PHY)
GMAC mode (RGMII, external PHY)
Let the DTS property be boolean instead of string
where EPHY mode is the default.
Fix how the properties are written
for all DTS that use them,
and add missing nodes where applicable,
and remove useless nodes,
and minor DTS formatting.

DTS properties that match *-gpios are treated specially.
Use ngpios instead, as most GPIO drivers upstream do.
Fixes 5.10 DTS errors such as:

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.

The mt7620 doesn't have a pinmux group named spi_cs1. The cs1 is part
of the "spi refclk" group. The function "spi refclk" enables the second

clock and GPIO.

The Ralink USB PHY driver merged into mainline has a slightly different
device tree binding than the patch that was used with linux 4.9.
The new driver requires a `ralink,sysctl` node pointing to the `syscon`
node.
This patch also sets `#phy-cells` to 0, as recommended by the mainline
documentation [1].

Revert the changes I applied to aa5014dd1a ("ramips: mt7620n: enable
port 4 as EPHY by default").
The driver expects a node mdio-bus to be present, regardless of the
actual node status. If the node is missing the driver fails to load with
mtk_soc_eth 10100000.ethernet: no mdio-bus child node found
Disable port4 by default again. If the port is enabled but not present, a
"invalid port id 4" warning is shown during boot.

This commit makes the following modifications to ramips dts files:
1. Add clkctrl node to all dtsi files (although not used for now)
2. Add clocks and clock-names properties to some nodes (usbphy, pci)
3. Add usbphy node for rt3050 (although not used for now)
4. Add clock-frequency to uart nodes in mt7621.dtsi and mt7628an.dtsi
These modifications, although not fully used at the moment, will make
it easier for FreeBSD to adopt and use LEDE ramips dts files with
minimal changes for easier maintenance.

* duplicate spacings
* empty lines at end of files and after last child nodes
* trailing and leading whitespace
* unnecessary and commented-out code
* missing empty lines between nodes and between properties and nodes
* unnecessary empty lines between nodes properties [1]
in .dts{,i} files, for ramips target.
[1] Some of empty lines in SOCs dtsi files were left untouched, because they seem to be there for a reason (readability?).
