There are some parts of BPI-R4Pro DTS that need to be changed. Currently
there should be not much users of the mainline-dts and we noticed some
things while openwrt integration.

Frank Wunderlich (3):
  arm64: dts: mediatek: mt7988a-bpi-r4pro: drop duplicate fan properties
  arm64: dts: mediatek: mt7988a-bpi-r4pro: update gpio-leds
  arm64: dts: mediatek: mt7988a-bpi-r4pro: rework pcie gpio-hog handling

On the official case the red LED is named ERR, the blue LED is named ACT.
Reflect these labels in function and set them default off.

From: Frank Wunderlich <frank-w@public-files.de>

The active-high property in base-dt cannot be overwritten and must be
set in separate overlay.
