fix a shutdown regression in intel_idle

Browse Source 
Fix a shutdown regression caused by 2a2d31c8dc ("intel_idle: open
broadcast clock event").  The clockevent framework can automatically
shutdown broadcast timers for hotremove CPUs.  And we get a shutdown
regression when we shutdown broadcast timer for hot remove CPU, so just
delete some code.

Also fix some section mismatch.
