In order to reduce flash size on some constrained boards this CL modifies the GPIO macro in gpio_list.h to change the name field from that listed 'name' to the concat of 'port' and 'pin'. Signed-off-by: Todd Broch <tbroch@chromium.org> BRANCH=samus BUG=chrome-os-partner:34489 TEST=manual 1. build with and without CONFIG_COMMON_GPIO_SHORTNAMES See 897 bytes savings with config option 2.
