[RFC v4 14/22] clockevents: clockevents_program_event(): turn clc into unsigned long

[Nicolai Stange]

Right now, being of type unsigned long long, the clc local variable in
clockevents_program_event() is unnecessarily wide as it gets cast to
unsigned long anyway.

Degrade clc's type to unsigned long and remove the now superfluous casts.
