nyan/rush/veyron: Align ChromeOS GPIOs to new model 

This CL makes slight changes to the ChromeOS-specific GPIO definitions
of Tegra and Rockchip boards to prepare them for new features in
depthcharge. It adds descriptions for the EC in RW and reset GPIOs,
changes the value Tegra writes into the (previously unused) 'port' field
to describe the complete GPIO information, and removes code to sample
some GPIOs that don't need to be sampled at coreboot time (to help
depthcharge detect errors and avoid using a stale value for something
that should always represent the current state).

BRANCH=None
BUG=None
TEST=None (tested together with depthcharge patches)
