zephyr: add initial gpio shim
Add the gpioget and gpioset commands to zephyr build. This requires
a minimum set of platform/ec gpio_ API functions. Add the minimum set of
gpio_ functions. More can be added later depending on future uses
BRANCH=none
BUG=b:169935802
TEST=verify gpioget and gpioset console command work on volteer
TEST=verify that posix-ec compiles without any named_gpios in DT
