KVM_GUEST in-turn selects ARCH_CPUIDLE_HALTPOLL and defines the requisite arch_haltpoll_{enable,disable}() functions. So remove the explicit dependence of HALTPOLL_CPUIDLE on KVM_GUEST, and instead use ARCH_CPUIDLE_HALTPOLL as proxy for architectural support for haltpoll. Also change "halt poll" to "haltpoll" in one of the summary clauses, since the second form is used everywhere else.
