[PATCH 2/2] arm64: dts: mediatek: mt7988a-bpi-r4pro: label gpio-hogs

[Frank Wunderlich]

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

GPIO hogs were tagged with name "?" in recent kernel versions (7.1+) due to
commit d1d564ec4992 ("gpio: move hogs into GPIO core").

7.0 showed the unit-name which behaviour is restored by patch [1], but
labeling the hog directly makes things easier.

gpiochip0: 84 GPIOs, parent: platform/1001f000.pinctrl, pinctrl_moore:
 gpio-0   (                    |tx-disable          ) in  lo
 gpio-1   (                    |mod-def0            ) in  hi IRQ ACTIVE LOW
 gpio-2   (                    |los                 ) in  hi IRQ
 gpio-12  (                    |cd                  ) in  lo IRQ ACTIVE LOW
 gpio-13  (                    |reset               ) in  hi IRQ ACTIVE LOW
 gpio-14  (                    |WPS                 ) in  hi IRQ ACTIVE LOW
 gpio-21  (                    |tx-disable          ) in  lo
 gpio-63  (                    |?                   ) out hi
 gpio-69  (                    |mod-def0            ) in  hi IRQ ACTIVE LOW
 gpio-70  (                    |los                 ) in  hi IRQ
 gpio-79  (                    |?                   ) out lo
 gpio-82  (                    |PHY reset           ) out hi ACTIVE LOW
 gpio-83  (                    |PHY reset           ) out hi ACTIVE LOW
