[PATCH] arm64: dts: marvell: fix number of GPIOs in Armada AP806 description

[Thomas Petazzoni]

The Armada AP806 has 20 pins, and therefore 20 GPIOs (from 0 to 19
included) and not 19 pins. Therefore, we fix the Device Tree
description for the GPIO controller.

Before this patch:

$ cat /sys/kernel/debug/pinctrl/f06f4000.system-controller:pinctrl/gpio-ranges
GPIO ranges handled:
0: mvebu-gpio GPIOS [0 - 19] PINS [0 - 19]
0: f06f4000.system-controller:gpio GPIOS [0 - 18] PINS [0 - 18]

After this patch:

$ cat /sys/kernel/debug/pinctrl/f06f4000.system-controller:pinctrl/gpio-ranges
GPIO ranges handled:
0: mvebu-gpio GPIOS [0 - 19] PINS [0 - 19]
0: f06f4000.system-controller:gpio GPIOS [0 - 19] PINS [0 - 19]

Fixes: 63dac0f4924b9 ("arm64: dts: marvell: add gpio support for Armada 7K/8K")

Note: this is a fix, that should go in the 4.13 cycle, as
63dac0f4924b9 was introduced in 4.13.
