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.
