[PATCH 03/13] ARM: tegra: Add gpio-ranges property

[Tomeu Vizoso]

Specify how the GPIOs map to the pins in Tegra SoCs, so the dependency is
explicit.

This currently will add a duplicated entry in the map from pins to gpios
in the pinmux controller but it should be harmless and will be fixed in a
later commit.

Signed-off-by: Tomeu Vizoso <tomeu.vizoso@xxxxxxxxxxxxx>

v2:	* Change number of gpios to 251 to match pinctrl-tegra124.c
	* Add note about duplicated mapping
	* Add the property to all the other Tegra SoCs
