thermal: cpuidle_cooling: fix kernel-doc warning and a spello

Correct one misuse of kernel-doc notation and one spelling error as
reported by codespell.

cpuidle_cooling.c:152: warning: cannot understand function prototype: 'struct thermal_cooling_device_ops cpuidle_cooling_ops = '

For the kernel-doc warning, don't use "/**" for a comment on data.
kernel-doc can be used for structure declarations but not definitions.
