Subject: [PATCH] pinctrl-bcm2835: Set base to 0 give expected gpio
 numbering

Signed-off-by: Noralf Tronnes <notro@tronnes.org>

SQUASH: pinctrl: bcm2835: Set base for bcm2711 GPIO to 0

Without this patch GPIOs don't seem to work properly, primarily
noticeable as broken LEDs.

Squash with "pinctrl-bcm2835: Set base to 0 give expected gpio numbering"
