[PATCH 3/9] cpuidle-haltpoll: condition on ARCH_CPUIDLE_HALTPOLL

[Ankur Arora]

The cpuidle-haltpoll driver and its namesake governor are selected
under KVM_GUEST on X86. In addition, KVM_GUEST also selects
ARCH_CPUIDLE_HALTPOLL and defines the requisite
arch_haltpoll_{enable,disable}() functions.

So remove the explicit dependence on KVM_GUEST, and instead use
ARCH_CPUIDLE_HALTPOLL as proxy for architectural support for
haltpoll.

While at it, change "halt poll" to "haltpoll" in one of the summary
clauses, since the second form is used everywhere else.
