cris: update comments for generic idle conversion

As of commit d53db20654bf ("cris: Use generic idle loop"), cris no
longer provides cpu_idle().

- On cris-v10, etrax_gpio_wake_up_check() is called from default_idle()
  instead of cpu_idle(),

- On cris-v32, etrax_gpio_wake_up_check() is not called from
  default_idle(), so remove this (copy-and-paste?) part.
