73eeac49be ramips: limit max spi clock frequency to 50 MHz
In the past few years, we have received several reports about SPI
Flash not working properly. This is caused by excessively fast
clock frequency. It's really annoying to fix them one by one. Let's
reduce these aggressive frequencies to 50 MHz. This is a safe and
suggested value in the vendor SDK.

3ea6125c50 ramips: mt7621-dts: describe switch PHYs and adjust PHY muxing
Currently, the MT7530 DSA subdriver configures the MT7530 switch to provide
direct access to switch PHYs, meaning, the switch PHYs listen on the MDIO
bus the switch listens on. The PHY muxing feature makes use of this.

This is problematic as the PHY may be attached before the switch is
initialised, in which case, the PHY will fail to be attached.

Since commit 91374ba537bd ("net: dsa: mt7530: support OF-based registration
of switch MDIO bus") on mainline Linux, we can describe the switch PHYs on
the MDIO bus of the switch on the device tree.

When the PHY is described this way, the switch will be initialised first,
then the switch MDIO bus will be registered. Only after these steps, the
PHY will be attached.

Describe the switch PHYs on mt7621.dtsi and remove defining the switch PHY
on the SoC's mdio bus node. When the PHY muxing is in use, the interrupts
for the muxed PHY won't work, therefore delete the "interrupts" property on
the devices where the PHY muxing feature is in use.

01996b785d ramips: clean up useless dts partition labels
The previous NVMEM eeprom conversions[1][2] left a lot of partition
labels that were no longer used. They can be removed now.

ramips: drop redundant label with new LED color/function format
Drop redundant label with new LED color/function format declared.
This was needed previously when the new format wasn't supported by
leds.sh functions script. Now that is supported this property
can be removed in favor of the new format.
