cris: update comments for generic idle conversion
As of commit 8dc7c5ecd8d0 ("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.
