[OpenWrt-Devel] [PATCH] bcm63xx: pinctrl: fix BCM6348 group0

[Daniel González Cabanelas]

The pinctrl group0 owns pins never used (at least in Openwrt) for any
pinmux.

Based on the info from the wiki for the BCM6348 Soc, this group only uses
the pin 32 needed for MII MDC:
https://openwrt.org/docs/techref/hardware/soc/soc.broadcom.bcm63xx/pinmux

Pins 33, 34, 35 and 36 are usually taken for GPIO buttons use. This is
causing an error which leads to non working buttons:
[    4.735928] gpio-keys-polled keys: unable to claim gpio 479, err=-22
[    4.742642] gpio-keys-polled: probe of keys failed with error -22

Fix it by deleting unneded pins in this group
