CRISv32: Add GPIO driver to the default configs
Fix a number of small issues visible when GPIO is enabled: - Correct missing default for !ETRAXFS in Kconfig - Remove information on number of bits for some Kconfigs related to the GPIO, they are different in ETRAX FS and ARTPEC-3 - Fix compile warning in ARTPEC-3 GPIO driver Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com>
