cpuidle: haltpoll: Take 'idle=' override into account
Currenly haltpoll isn't aware of the 'idle=' override, the priority is
'idle=poll' > haltpoll > 'idle=halt'. When 'idle=poll' is used, cpuidle
driver is bypassed but current_driver in sys still shows 'haltpoll'.
When 'idle=halt' is used, haltpoll takes precedence and makes
'idle=halt' have no effect.
Add a check to prevent the haltpoll driver from loading if 'idle=' is
present.
