CRIS: Drop code related to obsolete or unused kconfigs
Drop all code related to Kconfigs that don't exist. Fix one Kconfig where it was actually typo:ed (ETRAX_KGB_PORT2) Drop content related to CRIS v32 SoCs from etraxgpio.h headerfile, all use of GPIO for both ETRAX FS and ARTPEC-3 should now be through standard gpiolib instead.
