Significant changes in V2:
  * https://lore.kernel.org/lkml/20251016-openwrt-one-network-v1-0-de259719b6f2@collabora.com/
  * Only introduce labels in mt7981b.dtsi when required
  * Switch Airoha EN8811H phy irq to level rather then edge triggered
  * Move uart0 pinctrl from board dts to soc dtsi
  * Only overwrite constraints with non-default values in MT7981 bindings
  * Make SPI NOR nvmem cell labels more meaningfull
  * Seperate fixing and disable-by-default for the mt7981 in seperate
    patches

This series add various peripherals to the Openwrt One, to make it
actually useful an access point:

* Pcie express (tested with nvme storage)
* Wired network interfaces
* Wireless network interfaces (2.4g, 5ghz wifi)
* Status leds
* SPI NOR for factory data

Unsurprisingly the series is a mix of dt binding updates, extensions of
the mt7981b and the openwrt one dtb. All driver support required is
already available.

Sadly during testing i've found various quirks requiring kernel
arguments. Documenting those here both as note to self and making it
easier for others to test :)

* fw_devlink=permissive: the nvmem fixed-layout doesn't create a layout
  device, so doesn't trigger fw_devlink
* clk_ignore_unused: Needed when building CONFIG_NET_MEDIATEK_SOC as a
  module. If the ethernet related clocks (gp1/gp2) get disabled the
  mac ends up in a weird state causing it not to function correctly.
* pcie_aspm: ASPM is forced to enabled in 6.18-rc1, unfortunately
  enabling ASPM L1.1 ends up triggering unrecoverable AERs.

Patches are against the mediatek trees for-next branch
