kernel: config CONFIG_NO_HZ_FULL

Browse Source 
Moved CONFIG_NO_HZ_FULL config to each arch base.conf.

The config CONFIG_NO_HZ_FULL depends on CONFIG_HAVE_CONTEXT_TRACKING.
See https://github.com/torvalds/linux/blob/
a811c1fa0a02c062555b54651065899437bacdbe/kernel/time/Kconfig#L96

The context tracking is not supported on s390x yet.
See https://github.com/torvalds/linux/blob/
