Subject: [PATCH 5.16 0692/1017] staging: mt7621-dts: fix LEDs and pinctrl on GB-PC1 devicetree

From: Arınç ÜNAL <arinc.unal@...nc9.com>

[ Upstream commit 6256e18686158fa49e019297f990f1c1817aabf1 ]

Fix LED and pinctrl definitions on the GB-PC1 devicetree. Refer to the
schematics of the device for more information.

LED fixes:
- Change GPIO6 LED label from system to power as GPIO6 is connected to
PLED.
- Add default-on default-trigger to power LED.
- Change GPIO8 LED label from status to system as GPIO8 is connected to
SYS_LED.
- Add disk-activity default-trigger to system LED.
- Switch to the color:function naming scheme.
- Remove lan1 and lan2 LEDs as they don't exist.

Pinctrl fixes:
- Claim state_default node under pinctrl node.
- Change pinctrl0 node name to state-default.
- Change gpio node name to gpio-pinmux to respect
Documentation/devicetree/bindings/pinctrl/ralink,rt2880-pinmux.yaml.
- Sort pin groups alphabetically.

Misc fixes:
- Fix formatting.
- Use the status value "okay".
- Define hexadecimal addresses in lower case.
- Make hexadecimal addresses for memory easier to read.
