Move write protect GPIO handling to flash module
Write protect signal naming is now consistent across boards.
New CONFIG_WP_ACTIVE_HIGH is present on systems where the write
protect signal is active-high (e.g. Link). This will be used in the
next CL, which moves flash_get_protect() to flash_common.c
BUG=chrome-os-partner:15613
BRANCH=none
TEST=flashinfo properly reports WP signal status
