cs5535-clockevt: allow the MFGPT IRQ to be shared
Shared timer IRQs are not a good solution, however the Geode platform has no APIC, IRQs are a scarce resource and there is no technical reason to forbid it rightaway. Increased latencies and overhead due to sharing are still better than a driver refusing to load.

Hi again,
could you please take this, for linux-next?
Thanks, Jens
