Subject: init/Kconfig: move RCU_NOCB_CPU dependencies to choice
Every choice item of the "Build-forced no-CBs CPUs" choice had a
dependency to RCU_NOCB_CPU. It's more comprehensible if the choice itself
has the dependency instead of every choice item. The choice itself
doesn't need to be visible if there are no items selectable (i.e. on
arch/frv) or RCU_NOCB_CPU is not defined.
