This series continues mt7988 devicetree work

- Extend cpu frequency scaling with CCI
- GPIO leds
- Basic network-support (ethernet controller + builtin switch + SFP Cages)

depencies (i hope this list is complete and latest patches/series linked):

support interrupt-names because reserved IRQs are now dropped, so index based access is now wrong
https://patchwork.kernel.org/project/netdevbpf/patch/20250616080738.117993-2-linux@fw-web.de/

for SFP-Function (macs currently disabled):

PCS clearance which is a 1.5 year discussion currently ongoing

e.g. something like this (one of):
* https://patchwork.kernel.org/project/netdevbpf/patch/20250610233134.3588011-4-sean.anderson@linux.dev/ (v6)
* https://patchwork.kernel.org/project/netdevbpf/patch/20250511201250.3789083-4-ansuelsmth@gmail.com/ (v4)
* https://patchwork.kernel.org/project/netdevbpf/patch/ba4e359584a6b3bc4b3470822c42186d5b0856f9.1721910728.git.daniel@makrotopia.org/

full usxgmii driver:
https://patchwork.kernel.org/project/netdevbpf/patch/07845ec900ba41ff992875dce12c622277592c32.1702352117.git.daniel@makrotopia.org/

first PCS-discussion is here:
https://patchwork.kernel.org/project/netdevbpf/patch/8aa905080bdb6760875d62cb3b2b41258837f80e.1702352117.git.daniel@makrotopia.org/

and then dts nodes for sgmiisys+usxgmii+2g5 firmware

when above depencies are solved the mac1/2 can be enabled and 2.5G phy/SFP slots will work.

changes:
v4:
net-binding:
- allow interrupt names and increase max interrupts to 6 because of RSS/LRO interrupts
(dropped Robs RB due to this change)

dts-patches:
- add interrupts for RSS/LRO and interrupt-names for ethernet node
- eth-reg and clock whitespace-fix
- comment for fixed-link on gmac0
- drop phy-mode properties as suggested by andrew
- drop phy-connection-type on 2g5 board
- reorder some properties
- update 2g5 phy node
- unit-name dec instead of hex to match reg property
- move compatible before reg
- drop phy-mode

v3:
- dropped patches already applied (SPI+thermal)
- added soc specific cci compatible (new binding patch + changed dts)
- enable 2g5 phy because driver is now merged
- add patch for cleaning up unnecessary pins
- add patch for gpio-leds
- add patch for adding ethernet aliases

v2:
- change reg to list of items in eth binding
- changed mt7530 binding:
- unevaluatedProperties=false
- mediatek,pio subproperty
- from patternProperty to property
- board specific properties like led function and labels moved to bpi-r4 dtsi
