#1483084 — [PATCH v3 6/6] ARM: dts: bcm283x: add pinctrl group to &sdhci, drop pins from &gpio

As the alt3 group has no pins left after this
update drop the whole alt3 group from &gpio.

sorry it won't be that simple. The references needs to removed too :-(

> grep alt3 *.dts*
bcm2835-rpi-a.dts:	pinctrl-0 = <&gpioout &alt0 &i2s_alt2 &alt3>;
bcm2835-rpi-a-plus.dts:	pinctrl-0 = <&gpioout &alt0 &i2s_alt0 &alt3>;
