Future glados-derived boards are adding a WP_L GPIO input. Add support for this input, which will apply only if CONFIG_SYSTEM_UNLOCKED is not defined. Undefining CONFIG_SYSTEM_UNLOCKED will result in unpredictable WP GPIO behavior for all boards that currently exist, so it should only be undef'd right before MP FW is released. BUG=chrome-os-partner:50518, chrome-os-partner:50519 BRANCH=glados TEST=Verify 'ectool gpioget A13 --dev=1' always indicates a GPIO state '1' on an old chell_pd without WP_L input.
