[PATCH] ARM: tegra: fix naming in GPIO DT binding header

[Stephen Warren]

From: Stephen Warren <swarren@nvidia.com>

According to the Tegra TRM, GPIOs are aggregated into /ports/ of 8 GPIOs,
not into /banks/. Fix <dt-bindings/gpio/tegra-gpio.h> to correctly reflect
this naming convention. While this seems like silly churn, it will become
slightly more important once we introduce the GPIO binding for upcoming
Tegra chips.

It's not clear to me where this should be applied. This is technically
part of the GPIO controller bindings, in which case it'd need to go via
the GPIO tree. I'm fine with taking it through the Tegra tree, too, but
in case you agree that it should go through the GPIO tree:

I typically consider bindings part of the SoC code-base they related to, 
so I'd imagine this going through the Tegra tree. I didn't Cc LinusW on 
the patch because of that thinking and oversight, but have done so now 
just in case he feels strongly.

No strong opinion, only time I care is when we merge a new driver
and it #includes <dt-bindings/...>.

Take it through the tegra tree.
