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
chip select.

On reset, the pins of the "spi refclk" group are used as reference
clock and GPIO.

The former used compatibles aren't defined anywhere and aren't used by
the devicetree source files including them.

Since commit c1e7738988f5 ("checks: add gpio binding properties check")
dtc treats any *-gpios and *-gpio property as phandle at least during
checks. The only whitelisted property is nr-gpio.

Use ralink,nr-gpio in favour of ralink,num-gpios to get rid of false
positive warnings.

The cpu interrupt controller doesn't have a reg property, hence we
can't use a unit address in the node name.

We need a reg property if we are using a unit address.

I2c is supported on mt7620n like on mt7620a when checking the datasheet

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 aa5014dd1a58 ("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.

Fixes: FS#1428

According to the datasheet the mt7620n have a fixed switch configuration
with 5 ephy (10/100) port. No RGMII configuration is possible.

Drop the mdio node as well. Without RGMII, the mdio node doesn't make any
sense
