Subject: [PATCH 2/2] arm/tegra: Delete irq_to_gpio

irq_to_gpio is deprecated and in the process of being removed. Make that
happen now for ARM Tegra.

Signed-off-by: Stephen Warren <swarren@...dia.com>

I assume this will go into one of arm-soc.git's branches, but it depends
on the previous patch in this series to compile. Arnd, I see you already
have Grant's gpio/next tree in your repo as depends/gpio, so I assume
you'll just pick up and merge the latest version of Grant's tree before
applying this patch?

Both patches compiled with a number of Tegra boards enable and tested on
Harmony. All without Device Tree support.
